What is the volume of a cone with diameter of 9cm and a height of 5cm
To calculate the volume of a cone, you can use the formula:
V = 1/3 * π * r^2 * h
Given that the diameter is 9cm, the radius (r) would be half of the diameter, so r = 4.5cm. And the height (h) is 5cm.
Plugging the values into the formula:
V = 1/3 * π * (4.5)^2 * 5
V = 1/3 * π * 20.25 * 5
V = 1/3 * π * 101.25
V ≈ 106.1 cm^3
Therefore, the volume of the cone is approximately 106.1 cubic centimeters.
