Question

The formula for the volume of a cylinder is $V=\pi r^{2}h$, where $\pi =\frac{22}{7}$. Find $V$, when $r=3$ and $h=4$.

• A. $12\frac{2}{3}$
• B. $113\frac{1}{7}$
• C. $2\frac{5}{2}$
• D. $71\frac{3}{8}$

Answer 1

The correct option is B $113\frac{1}{7}$

$V=\pi r^{2}hr=3,h=4V=\frac{22}{7}\times 3\times 3\times 4=\frac{792}{7}=113\frac{1}{7}$
