Answer:-

Given: Curved surface area(S) = 880 cm2

height (h) =20 cm

Volume of the base of the cylinder = Pie × r^2 × h

:- S = 880 cm^2

:- 2pie× r × h = 880 cm^2

:- r = (880)/2pie × h

=> r = 7 cm

=> Volume of circle = pie × r^2 × h

= 3080 cm ^3 ans

Answer 2

$<b>Heya mate. (^_-). Solution below.$
====================================

[] Given -

Curved surface area (C.S.A) of a cylinder = 880 cm²

height (h) of the cylinder = 20 cm


[] Now, we know that C.S.A of any cylinder = 2πrh, where π = 22/7, r is the radius and h is the height.

→→→ 2πrh = 880

=> 2 × 22/7 × r × 20 = 880

=> 880/7r = 880

=> r = 880 × 7/880

=> r = 1 × 7

=> r = 7

•°• Radius of the cylinder = 7 cm.



[] Now, volume of any cylinder = πr²h


Then, volume of given cylinder

= πr²h

= 22/7 × 7 × 7 × 20

= 22 × 7 × 20

= 3080 cm³.

•°• Volume of the cylinder = 3080 cm³
