amorfide · Answer

you need to know the formula for the volume of a sphere

$$V=\pi(r)^{2}(h)$$

where h is the height, and r is the radius and V is volume

amorfide · Answer

then multiply your answer by $0.09

I meant cylinder not sphere

mathstudent55 · Answer

It sounds like the paint bucket is in the shape of a cylinder.
Use the formula for the volume of a cylinder to find the volume of the bucket of paint.
Then multiply the price of the paint per in^3 by the volume to find the total price of the bucket of paint.
