Question

12) The diameter of a bracelet is 17.8 cm.

Work out its circumference.
Round your answer to an appropriate degree of accuracy.

Answer 1

The formula for the circumference of a circle is C = πd, where d is the diameter of the circle and π (pi) is a constant approximately equal to 3.14.

Substituting the given value, we get:
C = πd
C = 3.14 x 17.8 cm
C = 55.892 cm

Rounding to an appropriate degree of accuracy, we get:
C ≈ 55.9 cm
