B. 30 inches

Reason:
The radius of the circle would be 15pi because 30pi divided by 2 would be 15pi (the formula for circumference is 2 x pi x radius). Diameter would be 2x the radius, so 15pi x 2 = diameter = 30

The prism has a volume up to 150.find the length of the prism
Varvara68 [4.7K]

Step-by-step explanation:

We have to know that in order to solve for the volume of a rectangular prism, we have to use this formula: l * w * h. This stands for length multiplied by width multiplied by height.

<u>Step 1</u>

Let's look at the numbers we already have. The height of the prism is 4 feet and the width is 5 feet. When we multiply them together, we got 20 feet.

<u>Step 2</u>

The volume of this prism adds up to 150 square feet. To find the length of this prism, we have to divide 150 by 20.

150 / 20=7.5

Our final answer: l = 7.5 feet

We can check our answer by multiplying all the numbers together.

4 * 5* 7.5 = 150
