"परिमिती" च्या विविध आवृत्यांमधील फरक
Content deleted Content added
ओळ २४:
This approximation is within about 5% of the true value, so long as `a' is not more than 3 times longer than `'`b' (in other words, the ellipse is not too "squashed"):
ellipse perimeter (approx) = 2pi into square root of [(a squared+b squared)/2
Approximation 2 :
ओळ ३८:
h = (a-b)<sup>2</sup>/(a+b)<sup>2</sup>
Then, ellipse perimeter (approx) = pi(a+b)(1 + 3h/(10+square root of (4-3h))
