Help with circles plz
The formula for the circumference of a circle is C = 2 pi r, where r is the radius of the circle.  Recall that the radius of a circle is half the diameter.In the first circle, the diameter is 25 meters, so the radius is (25/2) meters.Thus, the circumference of this circle is C = 2 (3.14) (25/2)^2 meters.Simplify and evaluate this expression.Note that another formula for Circumference is  C = pi d, where d is the diameter.  So, you could directly substitute the given diameter, 25 meters, into this formula to determine the circumference:C = pi d = (3.14)(25 meters) = ? ...
