If a circle has a circumference of 6.28 inches, then what is the radius?

1 answer:

7 0

♥ R≈1 inch when solving for Radius.
♥ Look at it this way:
♥ r=C/2π
♥ =6.28/(2·π)
♥ =1

Answer:

(B) 9π in²

Step-by-step explanation:

I’m going to assume that by 6 inches you meant 6π inches.

If the circumference of a circle is 6π inches, then it’s radius will be half of 6 (because the circumference of a circle is $2\pi r$ ).

$6\div2=3$

So the radius is 3.

Now that we know the radius, we can find the area by using the equation $\pi r^2$ .

$\pi 3^2\\\pi9\\9\pi$

Hope this helped!
