Question

The height of a cylinder is 15cm and the curved surface area is 660 cm.find it's radius .

Answer 1

Heya!
Here's Your Answer
_________________________________

CSA Of Cylinder is 2*22/7*r*h

Height Of Cylinder is given 15 cm
Curved Surface Area is 660 cm
Radius Is To Be Found!

Now,
If We Put The Values On Formula,

CSA = 2*22/7*r*15
660=2*22/7*r*15
660/15=2*22/7*r
22=22/7*r
1/7 =r
Hence,
Radius is 1/7
