Henry Knows That The Circumference Of A Circle Is 18Pi

d=c/\pi d = c/π. If written instead in terms of the radius, the diameter is very simple; it's just twice as long: d = 2 r. d = 2r d = 2r. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) Area is the space contained within the circle's boundaries. It's also easy to find from any of the others.Transcribed Image Textfrom this Question.

This function assumes perfect physics, i.e., constant gravity, no air resistance, etc. >>> get_distance(0, 1) 0.0 >>> get_distanceDivide the 81 pi by pi, then square root it. (Use the formula for area of circle, which gives 81pi=pi*radius squared, but rearrange to find the radius). i.e. it's the square root of 81A circle with area 81 pi has a sector with a central angle of 120 degrees.

0.81 is really with regards to sqrt(3)/2 (kind of 0.866...). sin(x) = sqrt(3)/2 when x = pi/3 and 2pi/3

y = sin(x)

y' = cos(x)

x = pi/3

cos(pi/3) = 1/2

sin(pi/3) = sqrt(3)/2

y - sqrt(3)/2 = (1/2) * (x - pi/3)

2y - sqrt(3) = x - pi/3

2y = x + sqrt(3) - pi/3

2y + pi/3 - sqrt(3) = x

x = 2 * 0.81 + pi/3 - sqrt(3)

x = 1.62 + 3.1416/3 - 1.732
