Front

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

Back

The volume increases by a factor of four, since volume is proportional to the square of the radius (V ∝ r²).

Front

Calculate the volume of a cylinder with a radius of 2 cm and a height of 5 cm. Use π = 3.14.

Back

Volume = πr²h = 3.14 * (2 cm)² * (5 cm) = 62.8 cm³.

What is the relationship between the height and volume of a cylinder?

Back

The volume of a cylinder is directly proportional to its height; if the height increases, the volume increases.

How do you round the volume of a cylinder to the nearest tenth?

Back

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

Front

Find the volume of a cylinder with a radius of 3 m and a height of 4 m. Use π = 3.14.

Back

Volume = πr²h = 3.14 * (3 m)² * (4 m) = 113.04 m³.

Front

What is the effect of increasing both the radius and height of a cylinder on its volume?

Back

Increasing both the radius and height will significantly increase the volume, as both dimensions contribute to the volume calculation.

Front

If a cylinder has a volume of 100 cm³ and a height of 5 cm, what is the radius?

Back

Using the formula V = πr²h, rearranging gives r = √(V/(πh)) = √(100 cm³/(3.14 * 5 cm)) ≈ 2.52 cm.
