Question

What is the circumference of circle p? Express your answer in terms of π (pi).

Answer 1

Equation: C = 2
`\pi`r
Step 1.) C = 2 * 3.1415 * 17
Solution: 106.814

Answer 2

34πcm

Explanation:

The circumference of a circle is expressed as 2πr where PC the radius.

Radius of a circle is the line drawn from the centre of the circle to its circumference. According to the diagram, the line drawn from the centre P to the circumference C which is PC is the radius i.e PC = radius = 17cm.

Substituting the value of the radius into the formula of the circumference of a circle we will have;

Circumference = 2π(17)

Circumference = 34πcm (in terms of π)
