Question

Find the Perimeter Of a circle whose radius is 14cm​

Answer 1

88 cm

Explanation:

Perimeter = 2πr

=2(14)(22/7)

= 88 cm

Answer 2

87.97cm

Explanation:

This question is asking to solve for the circumference.

The formula for the circumference of a circle is:
`\pi*diameter`

To work this out you would first need to multiply the radius of 14 by 2, this gives you 28cm. This is because the radius is half of the diameter.

The final step is to multiply pi by the diameter of 28, this gives you 87.97cm (87.9645943). This is because the formula for the circumference of a circle is
`\pi * diameter`.

1) Multiply 14 by 2.

`14*2=28`

2) Multiply pi by the diameter.

`\pi*28^2=87.97 cm`
