How do you fund the circumference of circle when you know the area?
You dived the area by the circumference of the circle.
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
What is the relationship between the circumference of a circle and the area of a circle?
Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)
What is the surface area of a sphere whose great circle has a circumference of 40pi?
The great circle has circumference 40pi and we know circumference is 2pixr so 20 is the radius of the sphere. Now use this and the formula that surface area is 4pir^2 so the surface are is 4pi(20)^2. or pi(1600)

What is the area of a circle you can surround with 20 feet of fence?
Radius of a circle with 20' circumference = 20'/2pi = 3.18'Area of a circle with 3.18' radius = ((3.18')^2)pi = 31.8 square feet
Is the Area of a circle and circumference of a circle have the same thing?
No,Circumference is like the perimiter and Area is the whole circle.
What is is circumference of a circle is 6.28. What is the area of the 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.
Is the circumference and area of a circle the same?
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.
