Question

A circle has a donated of 4.5cm a larger circle has a diameter of 24cm what is the aporximent diffrent in the circumference of the two circles

Answer 1

difference ≈ 61.3 cm

Explanation:

the circumference (C) of a circle is calculated as

C = πd ( d is the diameter ) , then

difference = 24π - 4.5π = 19.5π ≈ 61.3 cm ( to 1 dec. place )
