How To Solve D=182 X 3.14 X ? =56.52

Answer Question

1 Answer - Sort by: Date | Rating

    2*3.14*__ = 56.52
    __ = 56.52/(2*3.14)
    __ = 9.

    Apparently, your 56.52 is the circumference of a circle whose diameter (D) is 18. D is twice the radius (R), which is apparently 9. The formula for the circumference is
    C = 2*Pi*R  or
    C = Pi*D

    Since you already have D, there is really no point in dividing it by 2 just so you can put it into a formula that multiplies it by 2.
