\( A B C \) is an isosceles triangle inscribed in a circle of radius \( r \). If \( A B=A C \) and \( h \) is the altitude from \( A \) to \( B C \), then the \( \triangle A B D \) has perimeter \( P=2\left(\sqrt{2 h r-h^{2}}+\sqrt{2 h r}\right) \) and area \( A=\ldots \). Also, \( \lim _{h \rightarrow 0} \frac{A}{P^{3}}=\ldots \)https://bit.ly/YTAI_PWAP https://www.pw.live
