2πrh=220
or,πrh=110
or,rh=35
or,r=35×10/65
or,r=5.3
the volume is πr^2h=22/7×53/10×53/10×65/10
=573.84 cm^3

think that, the radious is = r
2πrh = 220
or , r = 220 × 7 ÷ 22 × 14×2
or,. r = 5/ 2 = 2.5 cm
the volume is = {22 ×(2.5)^2 × 6.5} / 7 =(22× 6.25 × 6.5) / 7 = 127 .6785 cc
hope it can help you
