A professional baker uses a chocolate mold to make decorations for cakes. One chocolate mold is in the shape of a cone and has a diameter of 2 cm and a height of 6 cm. What volume of chocolate, in cubic centimeters, is needed to make a solid chocolate cone? Use 3.14 for π .(1 point) Responses 6.28 cubic centimeters 6.28 cubic centimeters 18.84 cubic centimeters 18.84 cubic centimeters 12.56 cubic centimeters 12.56 cubic centimeters 37.68 cubic centimeters
To calculate the volume of a cone, we can use the formula:
Volume = (1/3) * π * r^2 * h
Given that the diameter of the chocolate mold is 2 cm, the radius would be half of that, which is 1 cm. The height of the chocolate mold is 6 cm.
Plugging in the values into the formula:
Volume = (1/3) * 3.14 * 1^2 * 6
= (1/3) * 3.14 * 1 * 6
= 6.28 cubic centimeters
Therefore, the volume of chocolate needed to make a solid chocolate cone is 6.28 cubic centimeters.
Volume = (1/3) * π * r^2 * h
Given that the diameter of the chocolate mold is 2 cm, the radius would be half of that, which is 1 cm. The height of the chocolate mold is 6 cm.
Plugging in the values into the formula:
Volume = (1/3) * 3.14 * 1^2 * 6
= (1/3) * 3.14 * 1 * 6
= 6.28 cubic centimeters
Therefore, the volume of chocolate needed to make a solid chocolate cone is 6.28 cubic centimeters.
A sandcastle mold is in the shape of a cone, with a diameter of 4 meters and a height of 6 meters. What volume of sand is needed to fill the mold? Use 3.14 for π .(1 point) Responses 75.36 cubic meters 75.36 cubic meters 25.12 cubic meters 25.12 cubic meters 150.72 cubic meters 150.72 cubic meters 100.48 cubic meters 100.48 cubic meters
To calculate the volume of a cone, we can use the formula:
Volume = (1/3) * π * r^2 * h
Given that the diameter of the sandcastle mold is 4 meters, the radius would be half of that, which is 2 meters. The height of the sandcastle mold is 6 meters.
Plugging in the values into the formula:
Volume = (1/3) * 3.14 * 2^2 * 6
= (1/3) * 3.14 * 4 * 6
= 100.48 cubic meters
Therefore, the volume of sand needed to fill the mold is 100.48 cubic meters.
Volume = (1/3) * π * r^2 * h
Given that the diameter of the sandcastle mold is 4 meters, the radius would be half of that, which is 2 meters. The height of the sandcastle mold is 6 meters.
Plugging in the values into the formula:
Volume = (1/3) * 3.14 * 2^2 * 6
= (1/3) * 3.14 * 4 * 6
= 100.48 cubic meters
Therefore, the volume of sand needed to fill the mold is 100.48 cubic meters.
