The circumference of a quarter is approximately 7.536 cm.
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The circumference of a circle is given by the formula:
C = πd
where C is the circumference, d is the diameter, and π (pi) is a mathematical constant approximately equal to 3.14.
Substituting the given diameter of a quarter, which is 2.4 cm, into the formula:
C = πd
C = π(2.4 cm)
C = 7.536 cm
Therefore, the circumference of a quarter is approximately 7.536 cm.
