What is the radius of a circle with a circumference of 84 meters?
To find the radius of a circle with a given circumference, you can use the formula:
C = 2πr,
where C is the circumference of the circle and r is the radius.
In this case, the given circumference is 84 meters.
So, we can set up the equation as:
84 = 2πr
To solve for r, we need to rearrange the equation and isolate r. Divide both sides of the equation by 2π:
84 / (2π) = r
Using a calculator, we can evaluate the right side to get the approximate value of r. Let's use the value of π as approximately 3.14 for simplicity:
84 / (2 * 3.14) = r
Evaluating this expression:
r ≈ 13.37
Therefore, the radius of a circle with a circumference of 84 meters is approximately 13.37 meters.
