Question

the volume ofthe volume of a cylinder is 39600 cm cube and height is 14 cm find its lateral surface area and total surface area ​

Answer 1

Step-by-step explanation:

volume of cylinder =π r square h

39600=22/7× r square ×14

39600=22× r square ×2

r square =39600/22×2

r square= 39600/44

r square=900

r=30

lateral surface area=2πrh

• 2×22/7×30×14

• 2×22×30×2

•88×30

•2640 answer

total suface area =2πr(h+r)

• 2×22/7×30(14+30)

•. 2×22/7×30×44

• 60×22/7×44
