Using 3.14 as Pi the area of circle is: 0
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
area from circumference area = ( circumference2 / (4 * pi) ) area = 2.865 square feet (approx)
Circumference = 18.85 metres Area = 28.27 square metres.
You dived the area by the circumference of the circle.
Since 'circumference' refers to a circle, if the lake is a circle with an area of six acres, the circumference would be: 2,563 feet.
area = 9∏mm (approx. 28.26mm) circumference = 6∏mm (approx. 18.84mm)
No,Circumference is like the perimiter and Area is the whole circle.
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.
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
The circumference of a circle with radius of 6 is about 37.7
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
Circumference = 18.8 mArea = 28.3 m^2.
