hey the answer is. . . . . .
2 pi r = 88
r = 88/2 × 7/22
r = 14 cm
csa = 2pi r h
6512 = 2 × 22/7 × 14 × h
6512/2 × 7/22 × 1/14
h= 74 cm
vol = pi r ^2 h
= 22/7 × 14 × 74
= 3256cm^3
2 pi r = 88
r = 88/2 × 7/22
r = 14 cm
csa = 2pi r h
6512 = 2 × 22/7 × 14 × h
6512/2 × 7/22 × 1/14
h= 74 cm
vol = pi r ^2 h
= 22/7 × 14 × 74
= 3256cm^3

here
2·pi·r = 88
r = 44/pi
r = 14.012 cm
volume = pi·r^2·h
= 2·pi·r·h·r/2
= s·r/2
= 6512·14.012/2
= 45625.477 cm^3
