What is the formula for the volume of a composite figure?

Back

The volume of a composite figure can be found by adding the volumes of its individual parts. For example, if a composite figure consists of a cylinder and a hemisphere, the volume is V = V_cylinder + V_hemisphere.

Front

How do you calculate the volume of a cylinder?

Back

The volume of a cylinder is calculated using the formula V = πr²h, where r is the radius and h is the height.

Front

What is the formula for the volume of a sphere?

Back

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius.

Front

How do you find the volume of a cone?

Back

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

Front

What is the value of π (pi) to two decimal places?

Back

π (pi) is approximately 3.14.

Front

How do you find the length of an arc in a circle?

Back

The length of an arc can be found using the formula L = (θ/360) × 2πr, where θ is the central angle in degrees and r is the radius.

Front

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

Back

The diameter of a circle is twice the length of the radius. Therefore, d = 2r.

Front

How do you calculate the area of a circle?

Back

The area of a circle is calculated using the formula A = πr², where r is the radius.

Front

What is a composite figure?

Back

A composite figure is a shape that is made up of two or more simple geometric shapes.

Front

What is the formula for the volume of a hemisphere?

Back

The volume of a hemisphere is given by the formula V = (2/3)πr³, where r is the radius.
