Question

Calculate the volume of a cylindrical paint can with a diameter of 3 in and a height of 8 in.

Leave your answer in terms of tt.

Answer 1

V= 18 \pi

Explanation:

V=πr²h

The radius is half of the diameter

so the radius is 3/2

r= 1.5 in

Now plug in

V= \pi 1.5²(8 in)

V= 18 \pi

Answer 2

Volume = 18 * pi in^3 OR IF pi=3.14 THEN Volume = 56.52 in^3

Explanation:

Volume = Area(circle) * Height

Volume = pi*(diameter/2)^2 *Height

Volume = pi* 2.25 * 8

Volume = 18 * pi in^3

And if pi=3.14 then:

Volume = 56.52 in^3
