CPM Homework Help : INT2 Problem 11-83

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

Step 1:

Volume of Cylinder = (area of base)(height) = (πr²)(h) = (36π in³)(14.5 in) ≈ 1640 in³

Step 2:

$\frac{1640\;\text{in}^{3}}{1}\cdot\frac{1\;\text{gallon}}{231\;\text{in}^{3}}=...$

Answer:

$≈ 7.1$ gallons
