Solve the problem. Use 3.14 as the approximate value of $\pi$. Round to the nearest tenth unless instructed otherwise.
-A cylindrical drain pipe is $5 \mathrm{in}$. across the top and about $10 \mathrm{in}$. high. How many cubic inches of water could it hold?
A) 196.3 in. 3
B) 392.5 in. 3
C) 785.0 in. ${ }^{3}$
D) 314.0 in. 3

Question

Quizplus · Accepted Answer

The volume of a cylinder is given by the formula $V = \pi r^2 h$, where $r$ is the radius of the base and $h$ is the height. In this case, the radius is $5/2 = 2.5$ inches and the height is $10$ inches. So, the volume is:$$V = \pi (2.5)^2 (10) \approx 196.3 \text{ in}^3$$
