Question

the radius of a right circular cylinder is 7cm and its height is 14cm. find its curved surface area and total surface area.

Answer 1

CSA=2πrh
=>2*22/7*7*14
=>616cm²
TSA=πr²h
=>22/7*7*7*14
=>2156cm².

Hope this will help u

##############################

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
