Question

The curved surface area of cylinder is 1980 cm.sq. and the radius of its base is 15 cm.find height of cylinder

Answer 1

Answer:

Step-by-step explanation:CSA=2πrh

Therefore,1980=2π15h

1980×7/2×22×15=h

By solving

h=21cm

Answer 2

Answer:

21

Step-by-step explanation:

Curved surface area of cylider=2πrh

1980 = 2 x 22/7 x 15 x h

1980 x 7

_______ = h

2 x 22 x 15

21 = h

Height = 21 cm
