The circumference is obtained by multiplying the diameter by pi.

Perimeter = pi*diameter so 200*pi = 628.32 metres.

If "one meter" is the diameter, then the answer is one meter.

Area = pi*r2r = Diameter/2r = 6.5 meters/2= 3.25 meters--------------------------now,Area = pi(3.25 meters)2= 33 m2======
