circumference = 2 x π x radius
⇒ radius = circumference ÷ 2π
area = π x radius2
= π x (circumference ÷ 2π)2
= circumference2 ÷ 4π
= 122 ÷ 4π
= 36/π
≈ 11.46 square units.
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 if its circumference 12pi is: 113.1 units squared.
No,Circumference is like the perimiter and Area is the whole circle.
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi
The area of a circle with a 12-foot circumference is about 11.46 square feet.
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 if its circumference 12pi is: 113.1 units squared.
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or pi*diameter
The circumference and area of a circle with diameter of 12 inches are:C = 37.7 inchesA = 113.1 square inches
11.455 CM2
Area = pi*62 Circumference = pi*12 or 2*pi*6
?
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.
