Question

4. Find the circumference of a circle with radius 20 ft., rounded to the nearest tenth

Answer 1

C= 125.6

Explanation:

The formula to find the circumference is :

`c = 2\pi \: r`

So the equation is:

`c = 2(3.14 * 20)`

Simplify:

`c = 2 * 62.80`

Simplify:

`c = 125.6`

And it asks to round to the nearest tenth, but it is already rounded to the nearest tenth.

Hope this helps : )
