Question

A circle has a circumference of 7{,}8507,8507, comma, 850 units. What is the radius of the circle?

Use 3. 14 for pi and enter your answer as a decimal

Answer 1

To find the radius of a circle, you can use the formula for circumference: C = 2πr, where C is the circumference and r is the radius. In this case, the circumference is 7,850 units and we're using 3.14 for pi.

7,850 = 2 * 3.14 * r

Now, we'll solve for r:

7,850 = 6.28 * r

r = 7,850 / 6.28

r ≈ 1,250

So, the radius of the circle is approximately 1,250 units.
