The ratio of curved surface area and the total surface area of a cylinder is 2:3. Find the volume of
cylinder if it is given that total surface area of cylinder is 924 m?.
10. The sum of the radius and height of a cylinder is 48 cm and the total surface area of the cylinde​

Answer 1

Answer:

Given

2Π(r+h)

Πrh

=

3

2

⇒

r+h

h

=

3

2

Or 3h=2r+2h or h=2r

TSA=924 Then 2Πr(r+h)=924⇒2Πr(r+2r)=924⇒6×Πr

2

=924⇒r=7cm And h=14Tthe volume of the cylinder=Πr

2

h=

7

22

(7)

×14=2156cm
