Question

Find the radius of the cylinder. Round your answer to the nearest tenth.

Answer 1

Step 1: V = Bh Write the formula for volume

Step 2:

$$\begin{gathered} 564=\mathrm{\pi }{\left(\mathrm{r}\right)}^2(4.25)\left(\mathrm{Substitute}\right) \\ \frac{564}{4.25\mathrm{\pi }}={\mathrm{r}}^2 \\ \sqrt{\frac{564}{1.25\mathrm{\pi }}}=\mathrm{r} \end{gathered}$$

Step 3: $=6.49$ Use calculator

Final Answer: The radius is about $6.49mm$
