Answer 1

Answer:

The total surface of cylinder = 2πr(h+r)

radius = 10

height = 14

= 2πr( h+r )

= 2 × 3.14 × 10 × ( 14 + 10 )

= 2 × 3.14 × 10 × 24

= 1507.2 sq.cm

but here cylinder's lid is open so

area area of base should be subtracted

area of base of cylinder = πr²

= 3.14 × 10 × 10

= 314

so,

1507.2 - 314 = 1193.2 sq.cm
