Hint: To find the number of cones, first we will find the volume of the circular cylinder and divide it with the volume of one ice-cream cone.
So,
Number of cones volume of the circular cylinder ÷ volume of one ice-cream cone
= $\dfrac{{\pi \times 6 \times 6 \times 15}}{{\dfrac{1}{3} \times \pi \times 3 \times 3 \times 12 + \dfrac{{2\pi }}{3} \times {3^2}}} = \dfrac{{\pi \times 36 \times 15}}{{\dfrac{\pi }{3} \times \left( {108 + 54} \right)}} = 10$
Answer $10$ cones
Note: In these questions, make sure you take the volume of the entities and not the area or perimeter.
Remembering the volume formulas is often helpful.
