From the condition, we know the circumference and it is 8.2n, and we need to find the radius of the circle.
Let’s start by recalling the formula for calculating the circumference:
L = 2 * n * R.
The circumference is equal to the product of 2n by the radius of this circle.
Let’s express the radius of the circle from the formula. To do this, we divide both sides of the equality by 2n.
R = L / 2п.
We just have to substitute the values in the formula and make calculations:
R = 8.2п / 2п = 4.1.
Answer: 4.1 radius of a circle with a length of 8.2п.
