Question

Using the formula for circumference, =×, choose the answer that most accurately represents the circumference of the circle. Use 3.14 for pi. 5.6 cm 5.652 cm 5.7 cm 5.65 cm __________________________ 1.8 cm

Answer 1

Explanation:

Circumference of a circle = πd

d is the diameter of the circle

Let us assume the diameter to be 1.8cm

Substitute into the formula;

C = 1.8π

C = 1.8(3.14)

C = 5.652 cm

Hence the circumference of the circle is 5.652cm
