What is the height of the right circular cone 5.5 cm 11 cm 12 cm 9 cm
11 answers
The height of a right circular cone is not determined by the given measurements of its dimensions (i.e., the radius, slant height, or diameter). Therefore, it is not possible to determine the height of the cone using just these measurements.
Pick one of the answers
I apologize for the confusion. If I had to pick one of the given measurements as the height of the right circular cone, I would choose 12 cm. Keep in mind that this is an assumption and may not reflect the actual height of the cone.

To find the surface area of the cylinder, we need to calculate the sum of the areas of the two circular bases and the lateral surface area.
The formula for the surface area of a cylinder is:
Surface Area = 2πr² + 2πrh
Given that the radius (r) is 11 cm and the height (h) is 12 cm, we can substitute these values into the formula:
Surface Area = 2 * 3.14 * (11)² + 2 * 3.14 * (11) * (12)
Surface Area ≈ 2 * 3.14 * 121 + 2 * 3.14 * 11 * 12
Surface Area ≈ 6.28 * 121 + 6.28 * 11 * 12
Surface Area ≈ 759.68 + 839.52
Surface Area ≈ 1599.2 square centimeters
Rounded to one decimal place, the surface area of the cylinder is approximately 1599.2 square centimeters.
Therefore, the closest approximation from the given options is 1,099 square centimeters.

Adrian is painting the outside of a cylinder that he plants to use as a coffee table. The cylinder has a radius of 4 feet and a height of 3 feet. Adrian wants to paint all around the outside of the cylinder, including the top and bottom faces. In order to understand how much paint is needed he wants to know the surface area of the outside of the cylinder what is the surface area of the cylinder measured in square feet use 3.14 for pi and round your answer to the nearest tenth
To find the surface area of the cylinder, we need to calculate the sum of the areas of the two circular bases and the lateral surface area.
The formula for the surface area of a cylinder is:
Surface Area = 2πr² + 2πrh
Given that the radius (r) is 4 feet and the height (h) is 3 feet, we can substitute these values into the formula:
Surface Area = 2 * 3.14 * (4)² + 2 * 3.14 * (4) * (3)
Surface Area = 2 * 3.14 * 16 + 2 * 3.14 * 4 * 3
Surface Area = 100.48 + 75.36
Surface Area ≈ 175.84 square feet
Rounded to the nearest tenth, the surface area of the cylinder is approximately 175.8 square feet.
Therefore, the surface area of the outside of the cylinder is 175.8 square feet.

Eli is making a model castle out of clay one of the roof peaks is in the shape of a cone with a diameter of 14 inches and a slant height of 20 inches. What is the surface Area of the cone peak round your answer to the nearest hundredth use 3.14 for pi
To find the surface area of the cone peak, we need to calculate the lateral surface area.
The formula for the lateral surface area of a cone is:
Lateral Surface Area = πrℓ
Given that the diameter (d) is 14 inches, we can calculate the radius (r) by dividing the diameter by 2:
r = d/2 = 14/2 = 7 inches
And the slant height (ℓ) is 20 inches.
Substituting these values into the formula, we get:
Lateral Surface Area = 3.14 * 7 * 20
Lateral Surface Area = 439.6 square inches
Rounded to the nearest hundredth, the surface area of the cone peak is approximately 439.6 square inches.
Therefore, the surface area of the cone peak is approximately 439.6 square inches.

Find the volume of the cylinder millimeters round your answer to the nearest hundredth 13 mm 8 mm
To find the volume of a cylinder, we use the formula:
Volume = πr²h
Given that the radius (r) is 13 mm and the height (h) is 8 mm, we can substitute these values into the formula:
Volume = 3.14 * (13)² * 8
Volume = 3.14 * 169 * 8
Volume = 4249.12 cubic millimeters
Rounded to the nearest hundredth, the volume of the cylinder is approximately 4249.12 cubic millimeters.
Therefore, the volume of the cylinder is approximately 4249.12 cubic millimeters.
