Volume Review

Front

What is the formula for the volume of a cylinder?

Back

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

What does π (pi) represent in volume calculations?

Back

π (pi) is a constant approximately equal to 3.14, used to calculate the circumference and area of circles.

Front

How do you calculate the volume of a composite figure?

Back

Break the figure into simpler shapes, calculate the volume of each shape, and then sum the volumes.

Front

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

Back

Volume = π(3)²(5) = 3.14 * 9 * 5 = 141.3 cm³.

Front

What is the volume of a rectangular prism with length 4 m, width 3 m, and height 2 m?

Back

Volume = length × width × height = 4 × 3 × 2 = 24 m³.

Front

How many cubic meters are in a cubic centimeter?

Back

1 cubic meter = 1,000,000 cubic centimeters.

Front

What is the volume of a sphere formula?

Back

Volume = (4/3)πr³, where r is the radius.

Front

If a storage tank can hold 420 cubic meters, how many tanks are needed for 60,000 cubic meters?

Back

60,000 ÷ 420 = 142.86, so 143 tanks are needed.

Front

What is the volume of a cone formula?

Back

Volume = (1/3)πr²h, where r is the radius and h is the height.

Front

How do you round a volume to the nearest tenth?

Back

Look at the hundredths place; if it's 5 or more, round up.
