Front

What is the formula for calculating the volume of a pyramid?

Back

Volume = (1/3) * Base Area * Height

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

How do you find the measure of an angle using an algebraic equation?

Back

Set up an equation based on the relationships between angles and solve for the variable.

Front

What is the formula for the volume of a cylinder?

Back

Volume = π * r² * h, where r is the radius and h is the height.

Front

If two angles are complementary and one angle is 25 degrees, what is the measure of the other angle?

Back

The other angle is 65 degrees.

Front

If two angles are supplementary and one angle is 3x degrees and the other is 10x - 15 degrees, how do you find x?

Back

Set up the equation: 3x + (10x - 15) = 180 and solve for x.

Front

What is the diameter of a circle?

Back

The diameter is the distance across the circle through its center, equal to twice the radius.

Front

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

Back

The diameter is twice the radius (d = 2r).

Front

How do you round a number to the nearest whole number?

Back

Look at the first decimal place: if it's 5 or more, round up; if it's less than 5, round down.
