What is the formula for the volume of a pyramid?

Back

The volume V of a pyramid is given by the formula V = (1/3) * base area * height.

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

Front

How do you calculate the base area of a pyramid with a square base?

Back

The base area A of a pyramid with a square base is calculated as A = side², where 'side' is the length of one side of the square.

Front

What is the relationship between the height of a cone and its volume?

Back

The height of a cone directly affects its volume; increasing the height while keeping the radius constant increases the volume.

Front

If a cone has a radius of 3 cm and a height of 4 cm, what is its volume?

Back

Using the formula V = (1/3) * π * (3)² * (4), the volume is approximately 37.7 cm³.

Front

What is the significance of π in the volume formula for a cone?

Back

π (pi) is a constant that represents the ratio of the circumference of a circle to its diameter, and it is essential for calculating areas related to circles.

Front

How do you round the volume of a pyramid to the nearest whole number?

Back

To round the volume to the nearest whole number, look at the decimal part: if it's 0.5 or higher, round up; if it's less than 0.5, round down.

Front

What is the volume of a pyramid with a base area of 10 m² and a height of 3 m?

Back

Using the formula V = (1/3) * base area * height, the volume is V = (1/3) * 10 * 3 = 10 m³.

Front

What units are used to express volume?

Back

Volume is typically expressed in cubic units, such as cubic meters (m³), cubic centimeters (cm³), or liters.

Front

How does the volume of a cone compare to that of a cylinder with the same base and height?

Back

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