Question

Alice purchased paint in a bucket with a radius of 3.5 inches and a height of 8 inches The paint cost $0.05 per cubic inch. What was the total cost of the paint? Use 3.14 for pi. Round only your final answer to the nearest penny. Enter your answer in the box.

Answer 1

The correct answer for me was 15.39$

Answer 2

The volume of the bucket will be given by:
v=πr²h
Thus the volume of our bucket will be:
v=3.14×(3.5)²×8
v=46.465 in³
thus the cost of the bucket will be:
cost=(cost per cubic volume)×(volume of bucket)
cost=46.465(0.05)=$2.32325~$2.30
