The Cone

Front

What is a cone?

Back

A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the apex or vertex.

Front

What is the formula for the volume of a cone?

Back

The volume V of a cone is given by the formula V = (1/3)πr²h, where r is the radius of the base and h is the height.

Front

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

Back

The surface area A of a cone is given by the formula A = πr(r + l), where r is the radius of the base and l is the slant height.

Front

What is the difference between a right cone and an oblique cone?

Back

A right cone has its apex directly above the center of the base, while an oblique cone has its apex not aligned with the center of the base.

Front

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

Back

The diameter of a cone is twice the radius. If r is the radius, then the diameter d = 2r.

Front

What is the slant height of a cone?

Back

The slant height l of a cone is the distance from the apex to any point on the circumference of the base.

Front

How do you find the height of a cone using the Pythagorean theorem?

Back

If you know the radius r and the slant height l, you can find the height h using the formula h = √(l² - r²).

Front

What is a circular cone?

Back

A circular cone is a cone with a circular base, which is the most common type of cone.

Front

What is the relationship between the volume of a cone and a cylinder?

Back

The volume of a cone is one-third the volume of a cylinder with the same base and height.

Front

What is a composite cone?

Back

A composite cone is formed by combining two or more cones or other shapes, often used in real-world applications.
