Question

The volume of a cylinder is 289 pie in. and the height of the cylinder is 1 in. What is the radius of the​ cylinder?

Answer 1

Answer:

$radius = 17 \: inches$

Step-by-step explanation:

$volume \: of \: a \: cylinder = \pi \times {r}^{2} \times h \\ \\ r = radius \\ h = height =1 \: inch \\ \\ volume \: of \: cylinder = 289\pi {in}^{3} \\ 289\pi = \pi \times {r}^{2} \times 1 \\ 289 = {r}^{2} \\ r = \sqrt{289} \\ r = 17 \: inches$
