Circumference = 2Ï€r so r = circumference/2Ï€
Then area = πr2
You dived the area by the circumference of the circle.
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.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
The area of a circle that has a circumference of 16pi is: 201.1 units2
The area of a circle, if its circumference is 20π, is: 314.16 square units.
The area of circle with a circumference of 20 is: 31.83 units squared.
If the area of a circle is 28.26 the circumference is: 18.84 units.
The circumference of a circle when the area is 69cm2 is about 29.4 cm
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
