Question

Find the volume of the cylinder. use 3.14 for pi. a cylinder with radius 3 inches and height 12 inches.

a. 339.12 cu. in.
b. 113.04 cu. in.
c. 226.08 cu. in.
d. 1356.48 cu. in.

Answer 1

The volume of a cylinder with a radius of 3 inches and a height of 12 inches is calculated using the formula V = πr²h. By substituting the values and using 3.14 for π, we find the volume to be 339.12 cubic inches, which matches option a.

Step-by-step explanation:

To find the volume of the cylinder, we use the formula V = πr²h, where V represents volume, r is the radius, and h is the height of the cylinder. In this case, the given radius is 3 inches, and the height is 12 inches.

Substituting these values into the formula, we get: V = π * (3 inches)² * 12 inches

V = 3.14 * 9 * 12

V = 339.12 cubic inches.

Therefore, the volume of the cylinder is 339.12 cubic inches, which corresponds to option a.
