Answer 1

I hope answer will help you.

Answer 2

Answer:

the height of the cylinder = 21 cm

Step-by-step explanation:

Curved surface area of a cylinder is 1980 cm2 and radius of its base is 15cm.

π  = 22/7

Curved surface area of a cylinder = 2πRh

R = radius = 15cm

h = height

Curved surface Area = 1980 cm²

2(22/7)15h = 1980

=> h = (1980 * 7)/(44 * 15)

=> h = (132 * 7)/44

=> h = 3 * 7

=> h = 21

=> h = 21 cm

the height of the cylinder = 21 cm
