THE CIRCUMFERENCE OF A CIRCLE IS 25 pi(3.14) mm. Find the radius

Answer Question

1 Answer - Sort by: Date | Rating

    The circumference of the circle is 2pi(radius).
    If the circumference is 25pi, then the equation becomes:

    Circumference = 2pi(radius)
    25 pi = 2 pi (radius)
    25 = 2 (radius)
    12.5 = radius

    Hence the radius of the circle is 12.5mm
