Question

The circumference of a circle is 8π cm. What is the RADIUS of the circle?

Answer 1

The formula for radius is $R=\frac{C}{2\pi }$.

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.

$R=\frac{25.1327412287}{2\pi } =4$

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

Answer 2

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 =   $\frac{C}{2\pi }$

we have to;

$\pi$ = 3.14 (it is a cost)

C = 8$\pi$

C = 8 × 3.14

C = 25.12

then we replace in the formula;

r =   $\frac{25.12}{2\pi }$

r =  $\frac{25.12}{2*3.14}$

r =  $\frac{25.12}{6.28}$

r = 4.
