Question

You have a 1-gallon paint can in the shape of a cylinder. One gallon is 231 cubic inches. The radius of the can is 3 inches. What is the approximate height of the paint can? Use 3.14 for pi.

Answer 1

Answer is :

8

For IM..

Answer 2

The approximate height of the paint can is 8.2 in

Explanation:

we know that

The volume of the cylinder ( can of paint) is equal to

`V=\pi r^(2) h`

we have

`V=231\ in^(3)`

`r=3\ in`

`\pi=3.14`

Substitute the values and solve for h

231=(3.14)(3)^{2} h

h=231/(3.14*9)=8.2 in
