What is the definition of volume?

Back

Volume is the amount of space occupied by a substance or object, typically measured in cubic units.

Front

What units are commonly used to measure volume?

Back

Common units for measuring volume include cubic centimeters (cm³), liters (L), and cubic meters (m³).

Front

Which label would NOT be appropriate for volume?

Back

Square miles is not appropriate for volume; it measures area.

Front

What is the formula for 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 approximate numerical value of Pi (π)?

Back

The approximate numerical value of Pi (π) is 3.14.

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 the formula for the volume of a sphere?

Back

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

Front

If the radius of a circle is 5 cm, what is its area?

Back

The area is A = π(5)² = 78.5 cm² (using π ≈ 3.14).

Front

If a cube has a side length of 3 cm, what is its volume?

Back

The volume of the cube is V = s³ = 3³ = 27 cm³.

Front

What is the relationship between area and volume?

Back

Area measures the extent of a surface, while volume measures the space occupied by a solid; area is two-dimensional, and volume is three-dimensional.
