Circumference (11/29)

Front

What is the formula for calculating the circumference of a circle?

Back

Circumference = π × diameter or Circumference = 2 × π × radius.

Front

If the diameter of a circle is 10 meters, what is the circumference?

Back

About 31.4 meters.

Front

What is the relationship between diameter and radius?

Back

The diameter is twice the length of the radius (Diameter = 2 × Radius).

Front

What is π (pi)?

Back

π (pi) is a mathematical constant approximately equal to 3.14, representing the ratio of the circumference of a circle to its diameter.

Front

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

Back

Diameter = Circumference / π.
