A uchun yechish
A=\pi r^{2}
r uchun yechish (complex solution)
r=-\sqrt{\frac{A}{\pi }}
r=\sqrt{\frac{A}{\pi }}
r uchun yechish
r=\sqrt{\frac{A}{\pi }}

Baham ko'rish
Klipbordga nusxa olish
\frac{A}{\pi }=r^{2}
\pi va \pi ni qisqartiring.
\frac{1}{\pi }A=r^{2}
Tenglama standart shaklda.
\frac{\frac{1}{\pi }A\pi }{1}=\frac{r^{2}\pi }{1}
Ikki tarafini \pi ^{-1} ga bo‘ling.
A=\frac{r^{2}\pi }{1}
\pi ^{-1} ga bo'lish \pi ^{-1} ga ko'paytirishni bekor qiladi.
A=\pi r^{2}
r^{2} ni \pi ^{-1} ga bo'lish.
