Answer :

The radius of the circle with a circumference of 68 inches is 10.82 inches.

To find the radius of a circle when given its circumference, you can use the formula:

Circumference = 2 × π × Radius

Here, the circumference is given as 68 inches. Rearranging the formula, we can solve for the radius:

Radius = Circumference / (2 × π)

Substituting the given circumference value:

Radius = 68 inches / (2 × π)

= 10.82 inches

Therefore, the radius of the circle with a circumference of 68 inches is approximately 10.82 inches.

To get the radius from the circumference, you must first find the diameter.
(Radius=Half of the circle, inside width)
(Diameter= The entire width of the inside of the circle)
(Circumference= the length of the outer ring of the circle)
How to calculate:
Radius *2=Diameter
Diameter* Pi= circumference
Circumference/Pi=Diameter
Diameter/2=Radius

So, we take 68, and divide it by the first 3 digits of Pi, with is 3.14
We get a number that can be rounded 1 hundredth up to 21.65
Take that number (which now represents the diameter) and divide it by 2 in order to get the radius. 21.65/2=10.825
You can round that off to either 10.8, or 10.83
~Hope this helps!
