Question

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

Answer 1

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

Answer 2

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

Answer 3

Yes, Thank you. I think I could do the rest by myself. Thank you again! c:
