Answer:

lateral surface area=2πrh

when radius not doubled=r

lateral = 2×22/7×r×h

lateral surface area =44rh/7

lateral surface area when doubled radius

doubled radius=2×r=2r

lateral surface area= 2×22/7×2r×h

lateral surface area=88rh/7

88rh/7÷44rh/7=88rh/7×7/44rh

the difference of lateral surface area=2times
