Front

How do you calculate the surface area of a cylinder?

Back

The surface area (SA) of a cylinder is given by: SA = 2πr^2 + 2πrh, where r is the radius and h is the height.

Front

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

Back

The surface area (SA) of a cone is given by: SA = πr^2 + πrl, where r is the radius and l is the slant height.

Define lateral area in the context of prisms and pyramids.

Back

Lateral area is the sum of the areas of all the sides (faces) of a solid, excluding the base(s).

Front

What is the surface area of a rectangular prism?

Back

The surface area (SA) of a rectangular prism is given by: SA = 2lw + 2lh + 2wh, where l is length, w is width, and h is height.

How do you find the surface area of a triangular prism?

Back

Front

What is the relationship between the slant height and the height of a pyramid?

Back

The slant height (l) is the distance from the apex of the pyramid to the midpoint of a side of the base, while the height (h) is the perpendicular distance from the apex to the base.

Front

How do you round surface area to the nearest tenth?

Back

To round to the nearest tenth, look at the hundredths place. If it is 5 or more, round up the tenths place by one. If it is less than 5, keep the tenths place the same.

Front

What is the surface area of a sphere?

Back

The surface area (SA) of a sphere is given by: SA = 4πr^2, where r is the radius.

Front

What is the difference between total surface area and lateral surface area?

Back

Total surface area includes the area of the base(s) and the lateral area, while lateral surface area only includes the area of the sides.
