Answer 1

Answer:

Radius (r) = 7 cm

height (h) = 10 cm.

Curved surface area of cylinder

2π/h

22

= 2 x 5 x 7 x 10

x 7 x 10 = 440 sq. cm.

7

Total surface area of cylinder

= 2tr(r + h)

22

= 2 x 5 x 7 (7+10)

= 44 x 17

= 748 sq.cm.

Ans. Curved surface area of cylinder is

440 sq cm and total surface area of cylinder

is 748 sq cm.
