Answer 2

Answer with explanation:

Volume of cone having (height =h) and (Radius =r) is given by

             $=\frac{\pi r^2 h}{3}$

Volume of a cone with radius 7.5 m and height 16 m

       $=\frac{\pi \times (7.5)^2 \times 16}{3}\\\\=\frac{22 \times 56.25 \times 16}{3\times 7}\\\\=\frac{19800}{21}\\\\=942.85 m^3\\\\=942 m^3{\text{Approx}$

Option A
