Scientists are drilling a hole in the ocean floor to learn more about the Earth’s history. Currently, the hole is in the shape of a cylinder whose volume is approximately 3600 cubic feet and whose height is 2.3 miles. Find the radius of the hole to the nearest hundredth of a foot. (Hint: Make sure the same units of measurement are used.)
The radius of the hole is ____ feet. (Round to the nearest hundredth.)

Convert height to ft scale
 1mi=5230ft
 2.3mi=2.3(5230)
 2.3mi=12029ft
Radius be rVolume V=πr²h
 3600/πh=r²
 3600/12029π=r²
 r²=0.095
 r=0.308ft≈0.31ft
