Question

The area of the curved surface of a cylinder is 4400cm^2, and the circumference of its base is 110cm. Find the height of a cylinder and the volume of the cylinder.. ..best explain answer will mark as brainliest...it's urgent...plz fast

Answer 1

Let radius of cylinder be r.

2*pi*r=110cm.....(1)

Curved Surface area=2*pi*r*h=4400cm^2......(2)

Simple:

Just divide 2 by 1

2*pi*r*h/2*pi*r=4400cm^2/110cm

h=40cm

Volume=pi*r*r*h

Given:

2*pi*r=110cm

=2*22/7*r=110cm

=r=110cm*7/44

=17.5cm

Volume =pi*r*r*h

=22/7*17.5*17.5*40

=38500cm^3

Thats the answer mate.
