Answer 1

Answer:

The answer is in picture

Answer 2

Answer:

Curved surface area = 2243.097 cm².

surface area of cylinder =  5013.98 cm²

Step-by-step explanation:

The given data :-

Height ( h ) of cylinder = 17 cm.

Volume ( V ) of cylinder = 23562 m³.

Volume of cylinder is given by

$V = \pi *r^{2}*h$

r = radius of cylinder.

23562 = π × r² × 17.

r = 21 cm.

i ) Curved surface area = 2 × π × r ×h = 2 × π × 21 × 17 = 2243.097 cm².

ii) surface area of cylinder

A = ( 2 × π × r² ) + ( 2 × π × r × h )

A = ( 2 × π × 21² ) + 2243.097  =  2270.884 + 2243.097  = 5013.98 cm²
