Solve the problem. Use 3.14 for $\pi$. Round to the nearest tenth.
-The foundation for a cylindrical storage shed is a cylinder $18 \mathrm{~m}$ in diameter and $3 \mathrm{~m}$ high. How many cubic $m$ of concrete are needed to build the foundation?
A) $339.1 \mathrm{~m}^{3}$
B) $1526.0 \mathrm{~m}^{3}$
C) $763.0 \mathrm{~m}^{3}$
D) $3052.1 \mathrm{~m}^{3}$

Question

Quizplus · Accepted Answer

The volume of a cylinder is calculated using the formula $ V = \pi r^2 h $. The radius $ r $ is half of the diameter, so $ r = 9 \mathrm{~m} $. The height $ h $ is $ 3 \mathrm{~m} $. Thus, $ V = 3.14 \times 9^2 \times 3 = 763.02 \mathrm{~m}^3 $, which rounds to $ 763.0 \mathrm{~m}^3 $.
