What is the formula for finding the area of a circle?

Back

Area = πr², where r is the radius of the circle.

Front

How do you determine if a table represents a proportional relationship?

Back

A table represents a proportional relationship if the ratio of y to x is constant.

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where their ratio is constant.

Front

If y = 3x, what does this tell you about the relationship between y and x?

Back

This indicates that for every unit increase in x, y increases by 3 units.

Front

What is the area of a circle with a radius of 10 feet?

Back

Area = π(10)² = 314.16 square feet.

Front

What does it mean for a table to be proportional?

Back

It means that as one quantity increases, the other quantity increases at a constant rate.

Front

How can you find the area of a circular parking lot?

Back

Use the formula Area = πr², where r is the radius of the parking lot.

Front

What is the significance of the constant of proportionality in a proportional relationship?

Back

It represents the factor by which one quantity changes in relation to another.

Front

If a table shows the values (1, 2), (2, 4), (3, 6), is it proportional?

Back

Yes, because the ratio of y to x is constant (y = 2x).
