Surface Area of Cylinders

Front

What is the formula for the total surface area of a cylinder?

Back

Total Surface Area = 2πr(h + r), where r is the radius and h is the height.

Front

What is the formula for the lateral surface area of a cylinder?

Back

Lateral Surface Area = 2πrh, where r is the radius and h is the height.

Front

What does 'lateral surface area' refer to in a cylinder?

Back

The area of the curved surface of the cylinder, excluding the top and bottom bases.

Front

If the diameter of a cylinder is 8, what is the radius?

Back

Radius = Diameter / 2 = 8 / 2 = 4.

Front

If a cylinder has a height of 10 and a radius of 3, what is the lateral surface area?

Back

Lateral Surface Area = 2πrh = 2 * 3.14 * 3 * 10 = 188.4.

Front

What is the total surface area of a cylinder with a radius of 5 and height of 10?

Back

Total Surface Area = 2πr(h + r) = 2 * 3.14 * 5 * (10 + 5) = 471.0.

Front

What is the total surface area of a cylinder with a diameter of 4?

Back

Total Surface Area = 2πr(h + r) = 2 * 3.14 * 2 * (h + 2). (Height must be provided to calculate.)

Front

What is the lateral surface area of a cylinder with a diameter of 6 and height of 4?

Back

Lateral Surface Area = 2πrh = 2 * 3.14 * 3 * 4 = 75.36.
