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
