What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

What does 'π' represent in the volume formula?

Back

π (pi) is a mathematical constant approximately equal to 3.14, representing the ratio of the circumference of a circle to its diameter.

Front

If a cylinder has a radius of 3 inches and a height of 5 inches, what is its volume?

Back

Volume = π(3 in)²(5 in) = 45π in³ ≈ 141.37 in³.

Front

How do you convert the volume of a cylinder from cubic inches to cubic centimeters?

Back

Multiply the volume in cubic inches by 16.387 to convert to cubic centimeters.

Front

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

Back

The diameter is twice the radius (d = 2r).

Front

If the height of a cylinder is doubled, how does that affect the volume?

Back

The volume also doubles, since volume is directly proportional to height.

Front

What is the volume of a cylinder with a radius of 4 cm and a height of 10 cm?

Back

Volume = π(4 cm)²(10 cm) = 160π cm³ ≈ 502.65 cm³.

Front

What units are used to measure the volume of a cylinder?

Back

Common units include cubic inches (in³), cubic centimeters (cm³), and liters (L).

Front

How do you estimate the volume of a cylinder?

Back

Use the formula V = πr²h and round π to 3.14 for quick calculations.

Front

What is the volume of a cylinder with a radius of 2 m and a height of 3 m?

Back

Volume = π(2 m)²(3 m) = 12π m³ ≈ 37.70 m³.
