Question

Approximately how many cubic feet of water could the tower hold?

Answer 1

Answer:

G. 7,500 cubic feet

Explanation:

1. Find the radius of the tower. $r=\frac{d}{2}=\frac{20}{2}=10$
2. The formula for the volume of a cylinder is $V=\pi r^2 h$.  Substitute the values. $V=\pi * 10^2 * 24$
3. Find the exponent. $V=\pi * 100 * 24$
4. Multiply. $V=\pi * 2400$
5. Estimate by setting $\pi$ equal to 3.14. $V=3.14*2400=7536$
6. The closest answer choice is G. 7,500 cubic feet.
