Find the radius of the hole to the nearest hundredth of a foot. ​ (Hint: Make sure the same units of measurement are​ used.)

Respuesta :

0.27 foot

Scientists are drilling a hole in the ocean floor to learn more about the​ Earth's history.

Shape of hole is cylinder.

Volume of that cylindrical hole = 3800 cubic feet

Height = 3.1 miles

1 mile = 5280 feet

3.1 miles= 3.1(5280)

             = 16368 feet

volume of cylinder = πr²h

r²=V/πh

r²=3800/(16368)π=0.073936

r=[tex]\sqrt{0.073936}[/tex]=0.27 foot
