Surface Area of Cylinders sutton

Front

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

Back

S = 2πrh + 2πr²

Front

What does 'r' represent in the surface area formula of a cylinder?

Back

The radius of the cylinder.

Front

What does 'h' represent in the surface area formula of a cylinder?

Back

The height of the cylinder.

Front

How do you find the diameter of a cylinder if you know the radius?

Back

Diameter = 2 × Radius.

Front

If the radius of a cylinder is 5 inches, what is the diameter?

Back

10 inches.

Front

What is the relationship between the radius and diameter of a circle?

Back

The radius is one-half of the diameter.

Front

Calculate the surface area of a cylinder with a radius of 3 inches and a height of 7 inches.

Back

S = 2π(3)(7) + 2π(3)² = 188.5 square inches.

Front

What is the unit of measurement for surface area?

Back

Square units (e.g., square inches, square centimeters).

Front

What is the lateral surface area of a cylinder?

Back

The area of the curved surface, calculated as 2πrh.

Front

If a cylinder has a height of 10 cm and a radius of 4 cm, what is its lateral surface area?

Back

Lateral Surface Area = 2π(4)(10) = 251.33 square centimeters.
