Mastering Cylinder Surface Area

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

• Surface Area = πr² + h

• Surface Area = 2πr + 2πrh²

• Surface Area = 2πr² + 2πrh

• Surface Area = 4πr² + 2πrh

Calculate the surface area of a cylinder with a radius of 3 cm and a height of 5 cm.

• 94.25 cm²

• 60 cm²

• 120 cm²

• 150.72 cm²

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

• 351.68 m²

• 300 m²

• 450 m²

• 200 m²

A cylinder has a surface area of 150 cm² and a height of 5 cm. What is its radius?

• Approximately 3.87 cm

• 2.5 cm

• 5.5 cm

• 4.2 cm

Find the surface area of a cylinder with a radius of 2 inches and a height of 7 inches.

• 113.04 square inches

• 94.25 square inches

• 78.40 square inches

• 50.24 square inches

How does increasing the height of a cylinder affect its surface area?

• The surface area of a cylinder increases as its height increases.

• The surface area of a cylinder remains constant regardless of height.

• Increasing the height of a cylinder decreases its surface area.

• The surface area of a cylinder is only affected by its radius, not its height.

If the radius of a cylinder is doubled, how does that affect the surface area?

• The surface area increases by a factor of 4.

• The surface area increases by a factor of 2.

• The surface area remains the same.

• The surface area decreases by a factor of 4.
