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.

Respuesta :

Answer:

The approximate height of the paint can is 8.2 in

Step-by-step explanation:

we know that

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

[tex]V=\pi r^{2} h[/tex]

we have

[tex]V=231\ in^{3}[/tex]

[tex]r=3\ in[/tex]

[tex]\pi=3.14[/tex]

Substitute the values and solve for h

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

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

Answer is :
