Circumference of the circular ground = 396m.
Also 2πr.
So,ATQ, 2πr = 396m
or 2 × 22/7 × r = 396m
or r = 396m × 7/22 × 2.
Therefore r = 63m.
Therefore diameter = 2r = 2×63m=126m.
Also, perimeter = circumference = 396m
Also 2πr.
So,ATQ, 2πr = 396m
or 2 × 22/7 × r = 396m
or r = 396m × 7/22 × 2.
Therefore r = 63m.
Therefore diameter = 2r = 2×63m=126m.
Also, perimeter = circumference = 396m
