Question

curved surface area of a cylinder is 1980 CM square and radius of its base is 15 cm find the height of the cylinder (=22/7)

​

Answer 1

Step-by-step explanation:

See The Formulae of Cuverd surface Area Of A Cylinder =2pi r l

2pi r l = 1980

= 2 x 22/7 x 15 x h

1980 x 7 /660 = 21

So Height Is 21 cm .
