CPM Homework Help : GC Problem 9-33

Cindy’s cylindrical paint bucket has a diameter of $12$ inches and a height of $14.5$ inches. If $1$ gallon $≈ 231\text{ in.}^3$ , how many gallons does her paint bucket hold?

Hint:

What is the area of the base of the bucket?

More Help:

Volume of a cylinder = (area of base)(height)

Step:

$\pi(6)^2\cdot14.5=522\pi\text{ in.}^3$

Answer:

$\frac{522\pi \text{ in}^3}{1}\cdot \frac{1\text{ gallon}}{231 \text{ in}^3}\approx 7.1\text{ gallons}$
