Question 1056206: Wood is removed from a wooden right circular cylinder of diameter 10cm and height 15 cm to form a right circular cone of the same base diameter and height.
(A) calculate the volume in cm^3 to 3 significant figures of wood removed.
(B) calculate the volume of wood removed as a percentage, to 3 significant figures of the original cylinders volume.

cylinder volume:
Pi*r^2*h = Pi*5^2*15 = 1178.10
cone volume:
Pi*r^2*h/3 = Pi*5^2*(15/3) = 392.70
:
A)Volume of wood removed: 1178.10-392.70 = subtract to get the answer
B)answer you got for A divided by 1178.10
