The formula to calculate the radius of a circle when you know the circumference is:
radius = circumference / (2 * π)
Given that the circumference is 12.56 miles and we use 3.14 for π, we can calculate the radius as follows:
radius = 12.56 / (2 * 3.14)
radius = 3.98 miles
Rounded to the nearest hundredth, the accelerator's radius is approximately 3.98 miles.
udrey works at a lab with a huge circular particle accelerator. It has been carefully engineered to have a circumference of 12.56 miles. What is the accelerator's radius?
Use 3.14 for 𝜋. If necessary, round your answer to the nearest hundredth.
