Here is your answer

Answer 2

9. the radious of the sphere is 10.5 cm
so the volume of the sphere is 4/3 π (10.5)^3 cm^3
and the volume of the cone is 1/3 π× (3.5)^2×3 cm ^3

so the number of the cones will be..

$\frac{ \frac{4}{3}\pi {(10.5)}^{3} }{ \frac{1}{3}\pi {(3.5)}^{2} \times 3 } \\ = \frac{4 \times 105 \times 105 \times 105 \times 10 \times 10}{35 \times 35 \times 3 \times 10 \times 10 \times 10 } \\ = 126$
so the number of cones is 126...【Answer】
