A circular pool cover has a circumference of 31.4 m what is the radius of the pool cover?
The formula to calculate the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle.
Given that the circumference of the pool cover is 31.4 m, we can set up the equation as:
31.4 = 2πr
Now we can solve for the radius:
31.4 = 2 * 3.14 * r
31.4 = 6.28r
r = 31.4 / 6.28
r = 5
Therefore, the radius of the pool cover is 5 meters.
