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.
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
