Volume of Cylinders

Front

What is the formula for the volume of a cylinder?

Back

V = B x h, where B is the area of the base and h is the height.

Front

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

Back

The area of the base of the cylinder.

Front

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

Back

The area of the base (B) is calculated using the formula B = πr², where r is the radius of the base.

Front

What is the relationship between the radius and diameter of a circle?

Back

The diameter is twice the radius (d = 2r).

Front

If the diameter of a cylinder is 4 m, what is the radius?

Back

The radius is 2 m.

Front

How do you find the volume of a cylinder given its height and diameter?

Back

First, find the radius from the diameter, then use the formula V = πr²h.

Front

What is the approximate value of π used in calculations?

Back

3.14.

Front

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

Back

The volume is 16π m³.

Front

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.

Front

What is the volume of a cylinder with a radius of 3 cm and a height of 5 cm?

Back

The volume is 45π cm³ or approximately 141.4 cm³.
