. What amount of ice cream in litres can fit into a waffle cone with a diameter of 9 cm and a height of 18 cm? (Imagine the ice cream fills the cone right to the top, and does not go above the edge of the cone.)
2. 0.42 L
c. 0.3 L
b. 0.46 L
d. 0.38 L
To calculate the volume of the ice cream that can fit into the waffle cone, we need to calculate the volume of the cone itself using the formula for the volume of a cone.
The formula for the volume of a cone is V = (1/3)πr^2h, where V is the volume, r is the radius, and h is the height.
Given that the diameter is 9 cm, the radius would be half of that, which is 4.5 cm. Converting this to meters, we get 0.045 m.
Using the formula, we can calculate the volume of the cone as follows:
V = (1/3)π(0.045^2)(18)
V ≈ 0.038 L
Therefore, the correct answer is option d. 0.38 L.
