We've chosen to implement one of the Ramanujan approximations in this perimeter calculator: Ellipse perimeter ≈ π * [3(a + b) - √((3a + b) * (a + 3b))]. The most well-known perimeter of a circle formula uses only one variable - circle radius: Have you ever wondered how many times your bike wheel will rotate on a ten-mile trip? Let P = perimeter and s(n) = a measured side. The other option is to use the law of sines if you have one side and the two angles that are formed by that side: so the triangle perimeter may be expressed as: Triangle Perimeter = a + (a / sin(β + γ)) * (sin(β) + sin(γ)). Rotate polygons about a point 8. How to find perimeter - perimeter formulas Usually the most simple and straightforward approach is to find the sum of all of the sides of a shape.
