CSA OF A CYLINDER -2PIE R H = 440
AND CIRCUMFERENCE = 2PIE R IS 110 COM
THEREFORE
440 = H * 110
H = 440/110
THEREFORE HEIGHT WILL BE- 4 CM.
ALSO RADIUS
2 PIE R H = 440
2* 22/7 *R *4=440
R = 440*7/2*22*4
R = 35/2
R = 17.5
NOW VOLUME WILL BE- PIE R^2 H
= 22/7 * 17.5 * 17.5 * 4
= 175 * 22
= VOLUME = 3850 CM^3
