WebApr 6, 2024 · The formulas linking the diameter and area of a circle reads area = π × (diam/2)2 and diam = 2 × √ (area / π). For instance, the diameter of a circle with unit area is approximately equal to 1.128 because diam = … WebLet's consider one of the triangles. The smallest one of the angles is dθ. Call one of the long sides r, then if dθ is getting close to 0, we could call the other long side r as well. The area of the triangle is therefore (1/2)r^2*sin (θ). Since θ is infinitely small, sin (θ) is equivalent to just θ. Then we could integrate (1/2)r^2*θ ...
