Cavalieri's principle states that volume formulas for pyramids and cones will also apply to both right and oblique solids, a<span>s long as the "matching" cross section areas are equal.
So we can use the formula V=bh regardless of the resulting shape. V = bh = </span>π(15 m)²(12 m) = 2700π m³ ≈ 8482.3 m³
