Area of a circle = pi R2If 'R' (the radius) is 1 meter, thenArea = pi (1)2 = pi = 3.142 square meters (rounded)
area is A=pi x R2, so 3.14 x 2(2.50)=15.7 the formula is a = pi x r squared . not r x 2 r = d / 2 ie 2.5/2 = 1.25 squared
Use the formula a = v2 / r, with v = velocity (speed, actually) in meters/second, r = radius in meters. The answer will be in meters per square second.
r=radius d=diameter r=d/2 r=2/2 r=1 meter
