To find the volume of a cone, we can use the formula V = (1/3)πr^2h, 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 by dividing the diameter by 2. So the radius (r) is 2 cm / 2 = 1 cm.

Using the given height of 6 cm, we can now calculate the volume:

V = (1/3)π(1^2)(6)
= (1/3)π(1)(6)
= (1/3)π(6)
= (1/3)(3.14)(6)
= 6.28 cubic centimeters

Therefore, the volume of chocolate needed to make the solid chocolate cone is 6.28 cubic centimeters.

To find the volume of a cone, we can use the formula V = (1/3)πr^2h, 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 by dividing the diameter by 2. So the radius (r) is 4 meters / 2 = 2 meters.

Using the given height of 6 meters, we can now calculate the volume:

V = (1/3)π(2^2)(6)
= (1/3)π(4)(6)
= (1/3)π(24)
= (1/3)(3.14)(24)
= 25.12 cubic meters

Therefore, the volume of sand needed to fill the sandcastle mold is 25.12 cubic meters.

To find the volume of a cone, we can use the formula V = (1/3)πr^2h, where r is the radius and h is the height.

Given that the radius of the cone is 5 inches and the height is 15 inches, we can calculate the volume:

V = (1/3)π(5^2)(15)
= (1/3)π(25)(15)
= (1/3)π(375)
= (1/3)(3.14)(375)
= 392.5 cubic inches

Therefore, the hanging flower vase can hold 392.5 cubic inches of water.
