Peano's formula is one method for approximating the perimeter of an ellipse. It involves computing the sum of an infinite series of terms, and so it is not exact but rather an approximation.
This formula is often used in situations where a good approximation is sufficient and where more precise methods, such as Kepler's formula, are not necessary.
Peano's formula is one of the many approximation formulas used for determining the perimeter of an ellipse
\(P\): the perimeter of the ellipse
\(a\): the length of the major axis
\(b\): the length of the minor axis
\(\pi\): A mathematical constant with an infinite decimal tail
The SI unit of perimeter is \(meter\text{ }(m)\)
Find \(P\)
