Subtopic: Right circular cylinder volume

Question Statement:

A cylindrical storage silo model has an internal radius of $r = 7\text{ cm}$ and a height of $h = 15\text{ cm}$. Taking $\pi \approx 3.14159$, the volume of the cylinder is ________ $\text{cm}^3$ (round off to two decimal places).

Answer Key:

2309.07

Step-by-Step Solution & Explanation

Volume of a right circular cylinder is: $V = \pi r^2 h = \pi \times (7)^2 \times 15 = 49 \times 15 \times \pi = 735 \pi \approx 2309.07\text{ cm}^3$
