Answer:
use formula
volume when height and radius is given
V=πr²h
volume when height and diameter is given
V=1/4×πd²h
3.14 x 9^2 x 14/3 = 1186.92
4/3 x 3.14 x 9^3 = 1526.04
1186.92 + 1526.04 = 2712.96 = 2713 cubic inches
Either i or -i, because nothing times itself will be negative so -538's square root is imaginary :)
