What is the volume of a cone with a diameter of 20cm and a height of 15cm ? Use 3.14 for pi. ( 1 point)
1,570 cubic centimeters
314 cubic centimeters
6,280 cubic centimeters
2,355 cubic centimeters
The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius and h is the height of the cone.
The radius of the cone can be found by dividing the diameter by 2:
r = diameter / 2 = 20cm / 2 = 10cm
Now we can calculate the volume of the cone:
V = (1/3)(3.14)(10^2)(15)
V ≈ (1/3)(3.14)(100)(15)
V ≈ (0.33333)(314)(15)
V ≈ 1566.666 cubic centimeters
Rounded to the nearest whole number, the volume of the cone is approximately 1,570 cubic centimeters.
Therefore, the correct answer is 1,570 cubic centimeters.
