area: pi times radius squared circumference: pi times radius

If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)

Circumference, C = 2*Pi*R Area, A = Pi * R^2 A = C Pi * R^2 = 2*Pi*R --> solve for R (radius) R = 2 So, the radius of a circle with area = circumference is two.

Circumference = 2*pi*radius Area = pi*radius2

The radius and area of a circle if the circumference is 157 are:r = 25A = 1,960

there is no constant that will calculate this, since circumference is calculated with only radius and area with radius squared. you will have to calculate the radius using the initial circumference and then the radius again for the new circumference (with the 50 added). then calculate an area for each radius..then you can see the increase.

28.26=area 18.84=circumference

They can't have the same value, since area has square units and circumference has linear units. But their number portions can be the same. The circumference and the area of a circle with a radius of 2 are both (4 pi), with the appropriate units.

Area = π × radius² → radius² = area/π → radius = √(area/π) Circumference = 2 × π × radius = 2 × π × √(area/π) = √(2² × π² × area/π) = √(4 × π × area)

The circumference is (2 pi) times (the radius), and the area is (pi) times (the radius squared).The same statements are true for any circle, not only this one, so this is actuallyquite a powerful answer.

Radius = square root of (area/pi) Circumference = 2*pi*radius
