Height of cylinder = 15 cm
Circumference of Base of cylinder = 88 cm
=> 2 pi r = 88
=> 2 × 22× r / 7 = 88
=> r = 88 × 7 / 44
=> r = 2 × 7
=> r = 14 cm
Radius of Base of cylinder = 14 cm
Now,
Volume = pi r^2 h
= 22 /7 × 14 × 14 × 15
= 22 × 2 × 14 × 15
= 44 × 210
= 9240 cm^3
Circumference of Base of cylinder = 88 cm

Now,

Circumference=2πr
88= 2πr
r= 88×7/22
r=14cm
Vol of cylinder=πr ×r×h
=22/7×14×14×15
=9240cm square
