Question

A circle has a diameter of 14cm Work out the circumference of this circle. Give your answer in terms of 3.14 and state it's units

Answer 1

C = 14π cm ( in terms of π )

the circumference (C) of a circle is calculated using the formula

C = πd ( where d is the diameter )

C = 14π cm ≈ 3.14 × 14 - 43.96 cm
