Question

17 Find the curved surface area of a cylinder circumference 1
of whose base is 88 cm and the height is 5 cm.​

Answer 1

Answer:

Circumference of circle = 2πr

88 = 2x22/7xr

88 = 44/7xr

44xr = 88x7

r = 88x7/44

r = 2x7

r = 14 cm

C.S.A. of cylinder = 2πrh

= 2x22/7x14x5

= 44/7x14x5

= 44/7x70

= 44x10

= 440 cm^2
