How do you find the radius of a cylinder if you know the diameter?

Back

The radius r is half of the diameter d. Therefore, r = d/2.

If a cylinder has a height of 10 cm and a diameter of 4 cm, what is its volume?

Back

First, find the radius: r = 4 cm / 2 = 2 cm. Then, V = πr²h = 3.14 * (2 cm)² * 10 cm = 125.6 cm³.

How does changing the height of a cylinder affect its volume?

Back

Increasing the height of a cylinder increases its volume, while decreasing the height decreases its volume, assuming the radius remains constant.
