Volume of Cylinders

Front

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

Back

Area of the base

Front

What is the formula for the volume of a cylinder?

Back

V = πr²h

Front

What is the value of π (pi) commonly approximated as?

Back

3.14

Front

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

Back

A = 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 radius of a cylinder is 3 cm and the height is 5 cm, what is the volume?

Back

V = π(3)²(5) = 45π cm³, approximately 141.4 cm³.

Front

How do you round a number to the nearest tenth?

Back

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

Front

What units are used for measuring volume?

Back

Common units include cubic centimeters (cm³), cubic inches (in³), and liters (L).

Front

What is the significance of the height (h) in the volume formula for a cylinder?

Back

Height determines how tall the cylinder is, affecting the overall volume.

Front

If a cylinder has a volume of 100 cm³ and a height of 10 cm, what is the area of the base?

Back

B = V/h = 100 cm³ / 10 cm = 10 cm².
