Front

What makes a relation not a function?

Back

If an input (x) has more than one output (y), it is not a function.

Front

Calculate the volume of a cone with a radius of 5 cm and a height of 10 cm using π = 3.14.

Back

What is the volume of a cone with a radius of 3 inches and a height of 6 inches?

Back

56.52 cubic inches

Front

Define direct proportionality in terms of a relationship between two variables.

Back

Two variables are directly proportional if increasing one variable results in a proportional increase in the other.

Front

What is the formula for the volume of a cylinder?

Back

V = π r² h

Front

How do you find the volume of a cone?

Back

Use the formula V = ⅓π r² h, where r is the radius and h is the height.

Front

What is the relationship between the volume of a cone and a cylinder with the same base and height?

Back

The volume of the cone is one-third that of the cylinder.

Front

If a cone has a radius of 4 cm and a height of 9 cm, what is its volume?

Back

V = ⅓π(4)²(9) = 48π cm³ or approximately 150.8 cm³.
