Circumference (MOD 35)

Front

What is the distance around a circle?

Back

Circumference

Front

What is the formula to calculate the circumference of a circle?

Back

Circumference = π × Diameter or Circumference = 2 × π × Radius

Front

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

Back

31.4 cm (using π ≈ 3.14)

Front

What is the diameter of a circle?

Back

The distance from one edge of a circle to another edge through the center.

Front

If the radius of a circle is 5 cm, what is the diameter?

Back

10 cm (Diameter = 2 × Radius)

Front

What is the relationship between diameter and radius?

Back

The diameter is twice the length of the radius.

Front

If a circle has a circumference of 62.8 cm, what is its diameter?

Back

20 cm (Diameter = Circumference / π)

Front

What is the circumference of a circle with a radius of 7 cm?

Back

43.96 cm (Circumference = 2 × π × 7)

Front

What unit is used to measure circumference?

Back

Units of length such as centimeters (cm), inches (in), or meters (m).

Front

If the circumference of a circle is 31.4 cm, what is the radius?

Back

5 cm (Radius = Circumference / (2 × π))
