Question

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 4300 cubic feet and whose height is 1.9 miles. Find the radius of the hole the nearest hundredth of a foot.

Answer 1

Volume of cylinder = pi*r^2 * h

4300 = (22/7)*(r^2)((1.9*5280)

r^2 =30100/220704 =0.1364

r = √0.0364 = 0.369 = 0.37 ft.
