Answer 2

Answer:

we have given that:-

Radius and height of cylinder are 7cm and 14cm respectively .

we have to find :

Curved surface area = ?

and

Total surface area of cylinder = ?

solution:-

we know that :-

Curved surface area of cylinder = 2πrh

and

Total surface area of cylinder = 2πr(r+h)

here,

C.S.Area = 2πrh

= 2× 22/7× 7 × 14

= 44×14

= 616 cm²

and ,

Total Surface area =2πr(r+h)

= 2×22/7 × 7 ( 7+14)

= 44 × 21

= 924 cm² answer
