A = 86.66 units2
The diameter of a circle that has a 33 cm circumference is: 10.5 cm (circumference divided by pi = diameter).
86.66 - 86.7 units squared
Circumference = 2 pi R = 33R = 33 / (2 pi)Area = pi R2 = pi (33)2 / (2 pi)2= (33)2 / (4 pi) = 86.66 square units
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.
Circumference = pi*33 = 103.6725576 or about 103.673 inches
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.
If d = 33, then c = 104
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
