The equation to find the total surface area of the cylinder is S = 2π(9)(h) + 2π(9)².
As per the question, the diameter of the cylinder is given as 18 inches, so we can calculate the radius (r) by dividing the diameter by 2:
r = 18 inches / 2 = 9 inches
The height of the cylinder is given as 4 inches.
To find the total surface area of a cylinder, we can use the following equation:
Total Surface Area = 2πrh + 2πr²
Now we can substitute the values into the equation to find the total surface area:
S = 2π(9)(h) + 2π(9)²
Therefore, the required equation is S = 2π(9)(h) + 2π(9)².

Twelve eggs cost $2.04 how much would 18 eggs cost?
Answer:
18 eggs would cost $3.06 :)
Step-by-step explanation:
Answer:
If 12 eggs cost $2.04, then figure out how much 1 egg costs. You do that by dividing the total by the amount = 0.17. Take that number and multiply by how many eggs and you'll get the total which is $3.06

c.terminal point (2square/2,square2/2);tan0=1/2
d.terminal point (1/2,3square/2);tan=3square
Answer:A
Step-by-step explanation: I did the quiz
The terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0 is 1.
What is a terminal point?The terminal point of a circle or circular path is the measure of the angle in degrees or radians over the circle, at the endpoint on the coordinate plane.
The equation for the angle is given as,
[tex]\theta=\dfrac{\pi}{4}\rm radians[/tex]
The terminal point and tan 0 has to be found out.As, the value of pi is 180 degrees. Put this value in the above expression as,
[tex]\dfrac{\pi}{4}=\dfrac{180}{4}=45^o[/tex]
Now, as the rotation of it clockwise from the x-axis in quadrant 1to get the degrees of the angle to the terminal point.
Let this is unit circle with radius 1. Therefore, from the unit circle attached below,
[tex]y=\sin(45)\times1=\dfrac{2}{\sqrt{2}}\\x=\cos(45)\times1=\dfrac{2}{\sqrt{2}}[/tex]
[tex]\tan (45)=1[/tex]
Hence, the terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0 is 1.

I need to understand how to solve this so please show work, thank you!
Answer:
Hopes this SS Helps you
Step-by-step explanation:
XOXO
KIT
Answer:
x = 2, x = 4
Step-by-step explanation:
Begin by letting f(x) = 0 , that is
x² - 6x + 8 = 0
Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (- 6)
The factors are - 2 and - 4 , since
- 2 × - 4 = + 8 and - 2 - 4 = - 6 , then
(x - 2)(x - 4) = 0
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 4 = 0 ⇒ x = 4

The volume of a cylinder is 80 cubic centimeters. If the diameter and
height of the cylinder are multiplied by 4/5, what is the volume of the new
cylinder?
Answer:2 yds and h
Step-by-step explanation:
The volume of the new cylinder will be equal to 40.96 cubic centimeters.
What is the volume of a cylinder?The amount of space inside a cylinder is its volume. You can find it by dividing the base area by the height.
The formula to calculate the volume of the cylinder is given below:-
V = πr²h
Given that volume of a cylinder is 80 cubic centimeters. The diameter and height of the cylinder is multiplied by 4/5. The new volume will be:-
Vi= πr²h = 80 cubic centimeters.
The new volume will be calculated as:-
Vn= π (4/5r)²(4/5)h
Vn = (64 / 125 ) πr²h
Vn = (64 / 125 ) x Vi
Vn = (64 / 125 ) x 80
Vn = 40.96 cubic centimeters.
Therefore, the volume of the new cylinder will be equal to 40.96 cubic centimeters.

Which justification can be used to demonstrate the graph is correct?
The justification (D) shading is to the left because (0, 0) does not satisfy the inequality option (D) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have inequality:
[tex]\rm x+3.5 < \dfrac{1}{10}(y-2)^2[/tex]
If plug (0, 0)
0 + 3.5 < 4/10
