Alice purchased paint in a bucket with a radius of 9 in. and a height of 9.5 in. The paint cost $0.09 per in3.

What was the total cost of the paint, rounded to the nearest cent?
Use 3.14 to approximate pi.

$ ?

Could someone please help me with this? And maybe explain it so I can be able to do it on my own sometime. Will fan

You need to find the volume first, then use $$total cost= cost / \inc^3 \times  volume$$
to find th evolume, use $$V=\pi r^2 h$$

so in your case, r=9, h=9.5, cost/inch3=0.09. rest should be easy
