Question

find the area of base and radius of cylinder if its curved surface area is 660 square centimetre and height is 21 centimeter​

Answer 1

Answer:

radius = 5 cm

area of base =78.57

Step-by-step explanation:

curved surface area= 2πrh

= 2*22/7*r*21

660 = 6*22*r

By solving for r we get

r = 5

and.

area of base = πr2

= 22/7*5*5

= 78.57sqcm
