Answer 15

volume of a sphere V=4/3pir^3, for 1/2 sphere it would be 2/3 pi r^3 for this it would be (2/3) (22/7)(125)=261.905 cubic feet. Now for the cylinder portion. V=pi r^2 h=(22/7) (25)(175)=13750 cu ft Total=14,011.9 rounding off 14,012. You should of got that when you plugged the numbers in and solved.
