Your English grammar appears to be very poor. I think you mean ' If the circumference of a circle is '6.28' , then what is the area?'. Remember the two circle equ'ns. C = 2 pi r A = pi r^(2) Since we know 'C' at 6.28, and pi = 3.14 Then we can find 'r' (Radius). Hence 6.28 = 2 x 3.14 x r r = 6.28/( 2(3.14)) r = 1 (one) Substituting into 'A' A = 3.14 (1)^(2) A = 3.14 units ^(2). That's doing the calculation in two steps. However, by algebraic reARRANGEMENT WE CAN DO IT IN ONE STEP. However, be careful with the algebra. C= 2 pi r r = C/2pi r^(2) = (C/2pi)^(2) Substituting A = pi (C/2pi)^(2) Cancel down by 'pi' Hence A = [C/2]^(2) / pi A = [ 6.28 / 2 ] ^(2) / 3.14 A = [39.4383/4] / 3.14 A = [9.8596]/3.14 A = 3.14 As before.
