Volume of a right circular cylinder is 6o L. If radius of cylinder is doubled, then what will be the increase in volume?  Choose the most appropriate option
A) 120 L B) 180 L C) 240 L D) 300 L E) 360 L
Pi∗r^2∗h=60   double the radius.....Pi∗(2r)^2∗h=Pi∗4∗r^2∗h=4∗60=240   IMPORTANT.. we are looking at the increase so   240-60=
