What is the volume, in cubic inches, of a cone with a diameter of 6 inches and a height of 7 inches? Round your answer to the nearest hundredth. ( 1 point )
The formula to calculate the volume of a cone is V = 1/3 * π * r^2 * h, where r is the radius and h is the height.
Given that the diameter of the cone is 6 inches, the radius (r) can be calculated by dividing the diameter by 2. So, r = 6 / 2 = 3 inches.
Plugging in the values, we get V = 1/3 * 3.14 * (3)^2 * 7 = 65.97 cubic inches.
Rounding to the nearest hundredth, the volume of the cone is approximately 66.00 cubic inches.
A coffee maker has a cone-shaped container to hold the coffee grounds. The radius of the container is 3 inches and the height is 7 inches. What is the volume, in cubic inches, of coffee grounds the container can hold? Round your answer to the nearest hundredth and use 3.14 for π

The formula to calculate the volume of a cone is V = 1/3 * π * r^2 * h, where r is the radius and h is the height.
Given that the diameter of the cone is 12 feet, we can find the radius (r) by dividing the diameter by 2. So, r = 12 / 2 = 6 feet.
Plugging in the values, we get V = 1/3 * 3.14 * (6)^2 * 15 = 564.36 cubic feet.
Rounding to the nearest tenth, the volume of water the tank can hold is approximately 564.4 cubic feet.

The formula to calculate the volume of a cone is V = 1/3 * π * r^2 * h, where r is the radius and h is the height.
Given that the diameter of the cone is 20 cm, we can find the radius (r) by dividing the diameter by 2. So, r = 20 / 2 = 10 cm.
Plugging in the values, we get V = 1/3 * 3.14 * (10)^2 * 15 = 1,570 cubic centimeters.
Thus, the volume of the cone is 1,570 cubic centimeters.

The formula to calculate the volume of a cone is V = 1/3 * π * r^2 * h, where r is the radius and h is the height.
Given that the diameter of the cone is 2 cm, we can find the radius (r) by dividing the diameter by 2. So, r = 2 / 2 = 1 cm.
Plugging in the values, we get V = 1/3 * 3.14 * (1)^2 * 6 = 6.28 cubic centimeters.
Thus, the volume of chocolate needed to make a solid chocolate cone is 6.28 cubic centimeters.

The formula to calculate the volume of a cone is V = 1/3 * π * r^2 * h, where r is the radius and h is the height.
Given that the diameter of the cone is 4 meters, we can find the radius (r) by dividing the diameter by 2. So, r = 4 / 2 = 2 meters.
Plugging in the values, we get V = 1/3 * 3.14 * (2)^2 * 6 = 25.12 cubic meters.
Thus, the volume of sand needed to fill the mold is 25.12 cubic meters.
