Question

Volume of the cylinder is 30 and height is 14cm find CSA of the cylinder

Answer 1

Answer:

4√330 sq. cm

Step-by-step explanation:

Here,

height of the cylinder is given.

h=14 cm

and volume is also given.

= 30 cubic cm

radius=?

Therefore,

Volume of cylinder= πr^2h

30=(22/7)*r*r*14

30=44*r*r

30/44=r*r

15/22=r^2

√(15/22)=r

rationalizing by √22

√330/22 cm =r

Now curved surface area of a cylinder

=2πrh

=2*(22/7)*√330/22*14

=4√330 sq. cm
