Question

What is the volume of a cylinder with a radius of 3 feet and a height of 4 feet? Use 3.14 for pi. Enter your answer in the box.

Answer 1

The volume of a cylinder refers to the number of cubic units that will exactly fill a cylinder. The volume of a cylinder can be found or calculate by using the formula 
V = πr²h, where r represents the radius of the figure.

In this exercise is given that the radius of a cylinder is 3 feet and the height is 4 feet, and it is asked to find its volume. In order to find the volume of the given cylinder, you should substitute the values for the radius and height into the previous mention formula.

V=πr²h
V=(3.14)(3 ft)²(4 ft)
V=(3.14)(9 ft²)(4 ft)
V=(3.14)(36 ft³)
V=113.04 ft³

The volume of the cylinder is 113.04 cubic feet.

Answer 2

volume of a cylinder = V = πr²h, r = radius and h = height.

if r = 3 and h = 4, then V = π3²(4) => V = 36π => V ≈ 113.1.
