(b) (c) (d) on the first part...these are all cones....

Volume of cone = (1/3)( pi) (radius of base)^2 * height of cone

Here's (b)......see if you can do (c) and (d)...if not...let me know

Volume = (1/3) (pi) (11^2) ( 16) ≈ 2027.37 in^3

For (b) (c) (d) on the second part

All of these are cylinders

Volume of cylinder = pi * (base radius)^2 * (cylinder height)

So

(b) [ the radius = 22/ 2 = 11 ]

Volume = pi * (11^2) ( 9) = 3421.19 ft^3

See if you can do (c) and (d), based on this.....
