Question

The circumference of a circular piece of plot is 440 m. Find its area.

hintHint:

Try to find radius of the circular piece.

The correct answer is: 15400 m2


    It is given that Circumference of the circular piece  = 440 m
    rightwards double arrow 2 straight pi r  =  440
    rightwards double arrow 2 (22 over 7) r = 440
    rightwards double arrow r = fraction numerator 440 cross times 7 over denominator 2 cross times 22 end fraction
    rightwards double arrow r = 70 m
    Area of the park = straight pi r2
    22 over 7 702
    = 15400 m2
