The area of a circle is given by the formula A =π r²
Therefore 121π = π r² : 121 = r² : r = √121 = 11
The circumference of a circle is given by the formula C = 2πr
C = 2 x 11π = 22π or 69.115 (to 3 decimal places)
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 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.
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
Circumference = 22pi/3 Radius = Circumference/(2pi) = 22pi/3*1/(2pi)= 11/3 Then area = pi*radius2 = pi*(11/3)2 = 121pi/9 = 42.24 square units.
the area can not be cubed. the area is always squared. volume is cubed. the formula for area is pie multiplied by radius squared. your formula for your circle is... A = 121pi in2 the radius in your circle is 11 inches the formula for circumference is two times pi times the radius C = 2 * (3.14159) * 11 your answer is 69.11498in
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.
