Answer:
Step-by-step explanation:
Given that,
Radius of a paint can, r = 4 inches
Height of a paint can, h = 15 inches
We need to find the volume of the paint can. We know that the shape of a paint can is in the form of cylinder such that the volume of cylinder is given by :
Substituting all the values we get
So, the volume of the paint can is 753.6 cubic inches.
