Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cyl

IrinaVladis [17]

Answer: option A

Step-by-step explanation:

The volume of a cylinder can be calculated with the formula:

$V=\pi r^2h$

Where r is the radius and h is the height of the cylinder.

The radius is diameter divided by 2, then:

$r=\frac{18ft}{2}\\\\r=9ft$

Substitute the radius into the formula. Then you get the following equation that can be used to find V, the volume of the cylinder:

$V=\pi (9)^2h$
