kavyamehra81: the c.s.a. of cylinder is 2πrh

adya18: oh so sorry, I am correction just now

kavyamehra81: and the t.s.a. is 2πr( r + h )

kavyamehra81: its okay

Answered by kavyamehra81

Curved surface area of cylinder = 2πrh
radius = 7cm
height = 15cm
= 2 × 22/7 × 7cm × 15 cm
= 44 × 15cm
= 660cm2
Total surface area = 2πr( r + h )
radius = 7cm
height = 15cm
= 2 × 22/7 × 7 ( 7cm + 15cm )
= 44 × 22cm
= 968cm2
hope it helps uh ❤
