So you divide the diameter by 2 to get the radius which would give you 10. Then multiply the radius twice so 10×10=100 thrn multiply by pi. 100x3.14=3.14

Answer:

1)88 2)44.5

Step-by-step explanation:

i'm not sure about 3 and 4

Answer:

1.) 88cm²

2.) 44.5cm²

3.) 141.37cm²

4.) 44cm²

Step-by-step explanation:

Alrighty, we're just going to do an abridged version, but if you need me to explain it more, I can:

1.) 6 x 8 ÷ 2 = 24

8 x 8 = 64

64 + 24 = 88

1.) 88cm²

2.) 2 + 2 + 3 = 7

7 x 5 ÷ 2 = 17.5

9 x 3 = 27

27 + 17.5 = 44.5

2.) 44.5cm²

3.) 3.14 x 3² = 28.27

3.14 x 6² = 113.1

28.27 + 113.1 = 141.37

3.) 141.37cm²

4.) 3.14 x 4² ÷ 2 = 25.135

4 x 2 = 8

8 x 9 ÷ 2 = 36

8 + 36 = 44

4.) 44cm²

if any of these are wrong, let me know

hope this helps:)

Step-by-step explanation:

Answer:

Step-by-step explanation:

we need to find the surface area of the shapes before adding them together. the triangles are 6*4 and since there are two, we do not need to divide by 2. (normally to find the area of a triangle it is base times height divided by 2)

so the area of the triangles are 24 units. Next we have the outer rectangles. 7*5=35. Since there are 2, we multiply by 2. Last we have the middle rectangle. 7*6=42.

the whole equation would be: 24+70+42= 136

so your answer would be B: 136.

Answer:

x = 1/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x + 4/9 = 7/9

Step 2: Subtract 4/9 from both sides.

x + 4/9 - 4/9 = 7/9 - 4/9

x = 1/3

Answer:

x = 1/3 (or) 3/9

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ (4/9) + x = 7/9

Then the value of x will be,

→ (4/9) + x = 7/9

→ x = (7/9) - (4/9)

→ x = (7 - 4)/9

→ x = 3/9

→ [ x = 1/3 ]

Hence, the value of x is 1/3.

7 is impossible It is impossible since there are no 6-inch pliers in the second basket.

the answer is 228 I was wrong when I said

I think the choices is wrong

Answer:

B. 228 meters square

Step-by-step explanation:

6 x 4 = 24

24 x 4 = 96

6 x 6 = 36

(8 x 6) / 2 = 24

24 x 4 = 96

96 + 96 + 36 = 228 square meters

Answer:

Diego is the most accurate, the probability of landing on B is 25% and he guessed 20% which is the closest to 25%

None of them match exactly because since they are not all equally sized, there is no way of telling exactly what the probability of landing on the sections are.

I hope this helps and sry if its wrong!

Answer:

it's not a right triangle

Step-by-step explanation:

5² + 13² = 14²

=> 25 + 169 = 196

=> 194 ≠ 196

The length of the triangles is 5 units , 13 units and 14 units and it is not a right angled triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measures of the sides of the triangle are 5 units , 13 units and 14 units

And , To determine if the triangle with sides 5, 13, and 14 is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.

If the theorem holds true for the given triangle, then it is a right triangle.

Let's check:

5² + 13² = 25 + 169 = 194

14² ≠ 194

Since 5² + 13² is not equal to 14², the triangle with sides 5, 13, and 14 is not a right triangle.

Hence , the triangle is not a right triangle

Answer:

28.3

Step-by-step explanation:

Answer:

28.3

Step-by-step explanation:

Use the Pythagorean theorem a^2 + b^2 = c^2

x is a, 17 is b, and 33 is c

x^2 + 17^2 = 33^2

Simplify:

x^2 + 289 = 1089

Subtract 289 from both sides:

x^2 = 800

Square root both sides:

x = √800

√800 is 28.28427, or 28.3

Answer:

41 feet

Step-by-step explanation:

For a radius r, the circumference is [tex]2\pi r[/tex] and the diameter is [tex]2r[/tex], so to get diameter, we can just divide the circumference by pi and we get the answer. Using 3.14 for pi we get:

[tex]127.74 / 3.14 = 41[/tex]

5/8 is 0.625 so that doesn’t work

Answer: f(x) = 64 * (3/4)^x

Step-by-step explanation: f(x)=ab^x

When x=0 f(x) = 64

64 = ab^0

b^0 =1 so

64 =a

f(x)=64 b^x

When x=1 f(x) = 48

48 = 64 *b

Divide by 64

48/64 =b

6/8 =b

3/4 =b

f(x) = 64 * (3/4)^x
