Question

What is the approximate circumference of the circle shown below

Answer 1

`C\approx44\: cm`

Explanation:

1) The Circumference of a Circle is its Perimeter given by
`C=2\pi r`. In this case, signed by a red line.

2) And
`\pi \approx3.14` with the given radius of 7 cm

3) Hence,

`C=2*3.14*7\Rightarrow C\approx44\: cm`

Answer 2

44

Explanation:

to find circumference of a circle you need to multiple r (7 in here) with 2 and pi

therefore the answer is : 2x7x3 = 42 or 44 approximately
