Geometry 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.

Front

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

Back

3.14

Front

How do you find the radius of a cylinder if you know the volume and height?

Back

Rearrange the volume formula: r = √(V / (πh)).

Front

What is the volume of a cylinder with a radius of 5 cm and height of 12 cm?

Back

Volume = π(5)²(12) = 300π cm³.

Front

If a cylinder has a volume of 300π cm³ and height of 12 cm, what is its radius?

Back

5 cm.

Front

How do you round a number to the nearest whole number?

Back

Look at the first decimal place: if it's 5 or more, round up; if it's less than 5, round down.

Front

What is the volume of a cereal box measuring 12 in x 6 in x 4 in?

Back

Volume = 12 * 6 * 4 = 288 in³.

Front

What is the volume of a snow cone with a radius of 3 cm and height of 10 cm?

Back

Volume = (1/3)πr²h = (1/3)π(3)²(10) = 30π cm³ ≈ 94.25 cm³.

Front

How do you compare the volumes of two cylinders?

Back

Calculate the volume of each cylinder using the formula and compare the results.

Front

What is the volume of a cylinder with a diameter of 10 cm and height of 5 cm?

Back

Volume = π(5)²(5) = 125π cm³.
