Problema Solution

scientist 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 to the nearest hundredth of a foot.(hint:make sure the same units of measurement are used.)

Answer provided by our tutors

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.
