Given:
The radius of the cylinder = 2 cm
Height of the cylinder = 5 cm
To find:
The volume of the cylinder.
Solution:
We know that, the volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=2,h=5[/tex] in the above formula, we get
[tex]V=\pi (2)^2(5)[/tex]
[tex]V=\pi (4)(5)[/tex]
[tex]V=20\pi [/tex]
Therefore, the volume of the cylinder is [tex]20\pi [/tex] cubic cm and its approximate value is 62.832 cubic cm.
I really need help! On either one!!
Answer:
512 cm3252 cm2Step-by-step explanation:
The first dimension to measure is length. Length is always the longest side of the box that has a flap. The next dimension is width. The width side also has a flap but is always the side shorter than the length. Measure the height of the package. Height is the only dimension without a flap.Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches. (Square inches can also be written in2.)Perimeter of the rectangle = PQ + QR + RS + SP
= b +l + b + l
= 2b +2l
Again,
ABCD is a rectangle. We know that the opposite sides of a rectangle are equal.
Perimeter of a Rectangle
AB = CD = 5 cm and BC = AD = 3 cm
So, the perimeter of the rectangle ABCD = AB + BC + CD + AD = 5 cm + 3 cm + 5 cm + 3 cm = 16 cm
It can be written as 5 cm + 5 cm + 3 cm + 3 cm
= (2 × 5) cm + (2 × 3) cm
= 2 (5 + 3) cm
= 2 × 8 cm
= 16 cm
We add length and breadth twice to find the perimeter of a rectangle.

find the range of the function f(x)=
[tex] \frac{ {x}^{2} + 3x + 5 }{2x - 1} [/tex]
Rewrite the numerator as
x ² + 3x + 5 = (x - 1/2)² + 4 (x - 1/2) + 27/4
Then
(x ² + 3x + 5) / (2x - 1) = 1/2 × (x ² + 3x + 5) / (x - 1/2)
… = 1/2 × ((x - 1/2)² + 4 (x - 1/2) + 27/4) / (x - 1/2)
… = 1/2 × ((x - 1/2) + 4 + 27 / (4 (x - 1/2)))
… = 1/2 x + 7/4 + 27 / (8 (x - 1/2))
which clearly has a non-removable singularity at x = 1/2, which is to say this function has a domain including including all real numbers except 1/2.
For every number other than x = 1/2, the function takes on every possible real numbers, since 1/2 x + 7/4 alone takes on all real numbers.
So:
domain = {x ∈ ℝ | x ≠ 1/2}
range = {x ∈ ℝ}

Use a net to find the surface area of the cone to the nearest
square centimeter. Use 3.14 for it.
23 cm
(The figure is not drawn to scale.)
The surface area of the cone is about cm2.
(Round to the nearest whole number as needed.)
Answer:
[tex]V=497.16\ cm^3[/tex]
Step-by-step explanation:
The attached figure shows a cone of radius 5 cm and height 19 cm. The formula for the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Substitute all the values,
[tex]V=\dfrac{1}{3}\times 3.14\times 5^2\times 19\\\\V=497.16\ cm^3[/tex]
So, the volume of the cone is equal to [tex]497.16\ cm^3[/tex].

1) What is the value of the expression 3 4 + 15.45 - 19.75 + 7.87?
Answer:
37.57
Step-by-step explanation:
34 + 15.45 - 19.75 + 7.87
34 + 15.45 = 49.45
49.45 - 19.75 + 7.87
49.45 + 7.87 = 57.32
57.32 - 19.75 = 37.57
4) If there was a coupon for 40% off, what is the final deconstructed
percent written as a DECIMAL? *. A.1.4
B.0.6
C.0.4
D.60%
Answer:
c
Step-by-step explanation:
Think of it like this. When you convert a percent to a decimal, just put a decimal point before the number. For example, 40%. You would put . before 40, making it 0.40, and you don't need the zero, so it becomes 0.4. For something like 8%, you would first put a zero before the 8, and then put a period before the zero, like so: 8%= 08%=0.08

A cereal box is being designed that needs to have dimension ratios of 1:1.5:4.2 and needs to have a volume of 14.49 cubic inches. What is the box's smallest dimension?
Answer:
2.2 inches
Step-by-step explanation:
smallest dimension = (smallest ratio / total ratio) x volume
(smallest ratio = 1
total ratio = 1 + 1.5 + 4.2 = 6.7
(1/6.7) x 14.49 = 2.2 inches

Answer:
[tex]\huge\purple {\boxed {m\angle FEG =23\degree}} [/tex]
[tex] \huge \orange {\boxed {m\angle FEH=113\degree}} [/tex]
Step-by-step explanation:
In the given circle, [tex] \overline{EG} [/tex] is diameter and [tex] \overline{EH} [/tex] is tangent at point E.
[tex]\therefore \widehat {EFG} [/tex] is a semicircular arc.
Since, measure of semicircular arc is 180°
[tex]\therefore m(\widehat {EFG})=180\degree... (1)[/tex]
[tex]\because m( \widehat {EF}) +m(\widehat {FG}) = m(\widehat {EFG}) [/tex] .... (2)
From equations (1) & (2)
[tex]\therefore 134\degree +m(\widehat {FG}) = 180\degree[/tex]
[tex]\therefore m(\widehat {FG}) = 180\degree-134\degree [/tex]
[tex]\therefore m(\widehat {FG}) = 46\degree [/tex]
By inscribed angle theorem:
[tex] m\angle FEG =\frac{1}{2} m(\widehat {FG} ) [/tex]
[tex] m\angle FEG =\frac{1}{2} \times 46\degree [/tex]
[tex]\huge\purple {\boxed {m\angle FEG =23\degree}} [/tex]
By tangent secant theorem:
[tex] m\angle FEH=\frac{1}{2} (46\degree +180\degree) [/tex]
[tex] m\angle FEH=\frac{1}{2} (226\degree) [/tex]
[tex] \huge \orange {\boxed {m\angle FEH=113\degree}} [/tex]

Esh deposits $3500 in an account that
earns 3.75% interest each year. After the
first year, Esh has $3631.25 in the account.
After the second year, Esh has $3767.42 in
the account, and after the third year Esh has
$3908.70 in the account.
Answer:
Compound interest
Step-by-step explanation:
The question requires us to determine if the interest earned is a simple or compound interest
Simple interest = amount deposited x time x interest rate
Future value with compounding = A( 1 + r)^n
A = amount deposited
r = interest rate
n = time
We would calculate the simple interest and the future value in year 2
Simple interest in year 2 = $3500 x 0.0375 x 2 = 262.50
Future value in 2 years with a simple interest = 262.50 + 3500 = $3762.50
Future value in year 2 with compounding = 3500 x (1.0375)^2 = $3767.42
The value provided in year 2 with compounding matches that provided in the question. Thus, it is compounding of interest that is done
3(x-5)=9 i don't know what to do
Answer:
x=8
Step-by-step explanation:
3(x-5)=9
3x-15=9
3x-15+15=9+15
3x=24
x=8
Answer:
x=8
Step-by-step explanation:
3(x-5) = 9
(3(x-5))/3 = 9/3
x-5 = 3
x-5+5 = 3+5
x=8
Two paths each 2m wide run across the middle of a rectangular field. If the area of the cross path is 196m and its length is 60m, find its breadth
Answer:
d=2m
Area(A)=196m
l=60m
Now,
A=d(l+b-d)
196=2(60+b-2)
196=2(58+b)
196=116+2b
2b=196-116
2b=80
b=40m
