If the height and the radius of the base of a cone are each increased by 100%, then the volume of the cone becomes

Twice the original

Four time the original

Eight times the original

Six times the original

Diameter of semi-circumference= r
New height=h+h = 2h
New radius=r+r = 2r
Volume= ? π* r^2 h
New volume= ? π (2r)^2 * 2h
New/original = 8/1
