Volume of Cylinders

Front

What is the formula for the volume of a cylinder?

Back

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

Front

What does the 'r' represent in the volume formula V = πr²h?

Back

The 'r' represents the radius of the base of the cylinder.

Front

What does the 'h' represent in the volume formula V = πr²h?

Back

The 'h' represents the height of the cylinder.

Front

How do you find the radius if you know the diameter?

Back

Radius = Diameter / 2.

Front

What is the diameter of a circle?

Back

The diameter is the distance across the circle through its center, equal to twice the radius.

Front

If a cylinder has a diameter of 10 inches, what is its radius?

Back

Radius = 10 inches / 2 = 5 inches.

Front

What is the approximate value of π?

Back

π is approximately 3.14.

Front

How do you calculate the area of the base of a cylinder?

Back

Area of the base = πr².

Front

What does the 'B' in the volume formula V = B x h stand for?

Back

'B' stands for the area of the base of the cylinder.

Front

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

Back

V = π(3 cm)²(5 cm) = 45π cm³ ≈ 141.4 cm³.
