Front

What are the components of the surface area of a cylinder?

Back

2 circles and 1 rectangle.

Front

How do you calculate the lateral surface area of a cylinder?

Back

Circumference of the circle times height.

Front

What is the formula for the area of a circle?

Back

π times the radius squared.

Front

If a circle has a radius of 8 cm, what is its diameter?

Back

16 cm.

Front

What is the area of a rectangle with a length of 4 cm and a width of 3 cm?

Back

12 cm².

Front

What is the formula for the circumference of a circle?

Back

2π times the radius.

Front

How do you find the total surface area of a cylinder?

Back

Add the area of the two circles and the lateral surface area.

Front

What is the height of a cylinder if its lateral surface area is 48 cm² and the radius is 4 cm?

Back

Height = 48 cm² / (2π * 4 cm) = 2 cm.

Front

What is the relationship between diameter and radius?

Back

Diameter is twice the radius.

Front

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

Back

The surface area increases by a factor of 4.
