When given a circumference how do you find the area?
A = C^2/(4 pi) The area of the circle is... The circumference squared... divided by 4... divided by pi If you already know the area, then you can multiply it by 4*pi, and then the square root of the product is equal to the circumference! C = (A*(4 pi))^(1/2)
How was it determined that the tangent of pi divided by 4 is 1?
As tan(x)=sin(x)/cos(x) and sin(pi/4) = cos(pi/4) (= sqrt(2)/2) then tan(pi/4) = 1

A circle with a end point of 2 times 5 time -1 times -4 would be the divided by pi. This would equal to a circumference of 1.59.
What is the area of a circle when the diameter is known?
let d be the diameter of the circe. So the radius is d/2 or half the diameter by definition. The area of the circle is Pi x r^2 so it is Pi (d/2)^2 this is (Pix d^2)/4 SO the area is Pi times the diameter squared all divided by 4
