To solve the problem, we need to find the ratio of the perimeters of a square and a circle when their areas are equal. Let's break this down step by step. Step 1: Set up the equations for the areasThe area of a square (A_square) can be expressed as:Asquare=a2where a is the ...
since when x varies from 3–√3 to 0 as y varies from 1 to the circles edge. So then I tried a substitutionx=2sinθx=2sinθ dx=2cosθdθdx=2cosθdθA=∫π304−(2sinθ)2−−−−−−−−−−√dxA=∫0π34−(2sinθ)2dx...
The formula is accurate for circles but only approximate for ellipses. The Ramanujan formula is more accurate for ellipses. Why is there no formula for the circumference of an ellipse? There is no exact formula for the circumference of an ellipse because the values or measurements of an ellipse...
2.) The goal of this problem is to find the area shared by the circles and . PART 1: Making use of symmetry, the shared area can be repre Find the area of the region that is inside the cardioid r = 4 + 4cos(theta) and outside the circle r = 6. Find ...

I tried to approach the problem by first parametrizing the great circle and then integrating the length of the longitudinal arcs between $B$ and $B'$, but I don't know how to express the angle between the great circle and the $xOy$ plane. I'm only aware of two special cases: when ...
