Step-by-step explanation:
Formula for calculating volume of cylinder is πr^2h
Outer r - inner r
πh. Outer^2-innrrR^2
22/7×30×8.5^2-7.5^2
=22/7×30×16.03
=22×30×2.29
=1519.4

Answer:
It will be 1507.2cm cube to me
Step-by-step explanation:
=3.14 x 30 x [(15/2) + (17/2)]
=3.14 x 30 x 7.5 + 8.5
=3.14 x 30 x 16
=50.24 x 30
=1507.2m cube
