Question

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

Answer 1

Answer:

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

Step-by-step 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

Answer 2

Answer:

V= 18 \pi

Step-by-step 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
