What is the volume of a cone with a diameter of 20 cm and a half of 15 cm
To find the volume of a cone, you need to know the radius and the height of the cone. The radius is half the diameter, so the radius of this cone is 20 cm / 2 = 10 cm. The height is given as 15 cm.
The formula to find the volume of a cone is as follows:
Volume = (1/3) * π * r^2 * h
Plugging in the values:
Volume = (1/3) * 3.14 * (10 cm)^2 * 15 cm
Volume = (1/3) * 3.14 * 100 cm^2 * 15 cm
Volume = (1/3) * 3.14 * 1500 cm^3
Volume = 1570 cm^3 (rounded to the nearest whole number)
Therefore, the volume of the cone is approximately 1570 cm^3.
