Front

What is the formula for finding the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

What does it mean for two angles to be complementary?

Back

Two angles are complementary if their measures add up to 90°.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if their measures add up to 180°.

Front

How do you find the volume of a composite figure?

Back

To find the volume of a composite figure, break it down into simpler shapes, calculate the volume of each, and then sum them up.

Front

What is the formula for the volume of a cylinder?

Back

Volume = π × radius² × height.

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(length × width + length × height + width × height).

Front

How do you find the missing angle in a triangle?

Back

The sum of the angles in a triangle is always 180°. Subtract the sum of the known angles from 180° to find the missing angle.

Front

What is the formula for the volume of a cone?

Back

Volume = (1/3) × π × radius² × height.

Front

What is the relationship between the angles in a linear pair?

Back

Angles in a linear pair are supplementary; they add up to 180°.

Front

How do you calculate the surface area of a cylinder?

Back

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