What is the volume of a cone with a diameter of 20 cm and a height of 15 cm?
To find the volume of a cone, we can use the formula V = (1/3) * π * r^2 * h, where r is the radius and h is the height of the cone.
Given that the diameter is 20 cm, the radius (r) is half of that, which is 10 cm.
So, the volume of the cone is V = (1/3) * π * 10^2 * 15.
Using π ≈ 3.14, we can now calculate the volume:
V ≈ (1/3) * 3.14 * 100 * 15
V ≈ 1570 cm^3.
Therefore, the volume of the cone is approximately 1570 cubic centimeters.
