Question

Find the height of a cylinder whose radius is 7 cm and the curved

surface area is 880 cm2

.​

Answer 1

Answer:

CSA of cylinder=2πrh

880=2×22/7×7×h

880=2×22×h

h=20cm

Answer 2

Curved surface area of the cylinder = 2πrh

Curved surface area of the cylinder = 880 cm^2

Now

2πrh= 880

2× (22/7)×7×h= 880

h= 880/44

h = 20 cm
