# Find the circumference of a circle with diameter of 22 units.

Diameter of a circle is the largest chord that is passing through the centre.

The circumference of a circle is the distance around the boundary of the circle.

## Answer: The circumference of a circle with diameter of 22 units is approximately equal to 69.08 units.

Consider a circle with radius 'r' units and diameter 'd' units.

**Explanation:**

d = 22 units (given)

Let the circumference be 'C'

Circumference of a circle is given as,

C = 2 π r

=> C = π d (since, 2r = d)

=> C = 3.14 × 22 (since, d = 22)

=> C = 69.08

### Thus, the circumference of a circle with diameter of 22 units is approximately equal to 69.08 units.
