Question

Find the missing dimension of the cylinder at the right. Round your answer to the nearest whole number.

$V=600,000c{m}^3$

Answer 1

Step 1: V = Bh Write the formula for volume

Step 2:

$$\begin{gathered} 600,000=\mathrm{\pi }{\left(\mathrm{r}\right)}^2\left(76\right)\mathrm{Substitute} \\ \frac{600,000}{76\mathrm{\pi }}={\mathrm{r}}^2 \\ \sqrt{\frac{600,000}{76\mathrm{\pi }}}=\mathrm{r} \end{gathered}$$

Step 3: $=50.1$Use calculator

Final Answer: The radius is about $50cm$
