The formula for radius is [tex]R=\frac{C}{2\pi }[/tex].

First we need to see what 8*π is, put it in your calculator and you will get . So now we know the exact circumference, so now put that into the equation to find the radius.

[tex]R=\frac{25.1327412287}{2\pi } =4[/tex]

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY!

Answer:

The answer is, 4 cm

Step-by-step explanation:

The radius of a circle can be calculated using the circumference, to find it we will use the following formula:

r =   [tex]\frac{C}{2\pi }[/tex]

we have to;

[tex]\pi[/tex] = 3.14 (it is a cost)

C = 8[tex]\pi[/tex]

C = 8 × 3.14

C = 25.12

then we replace in the formula;

r =   [tex]\frac{25.12}{2\pi }[/tex]

r =  [tex]\frac{25.12}{2*3.14}[/tex]

r =  [tex]\frac{25.12}{6.28}[/tex]

r = 4.
