$$v = \frac { 1 } { 3 } \pi r ^ { 2 } h$$

h uchun yechish (complex solution)

$$\left\{\begin{matrix}h=\frac{3v}{\pi r^{2}}\text{, }&r\neq 0\\h\in \mathrm{C}\text{, }&v=0\text{ and }r=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$\frac{1}{3}\pi r^{2}h=v$$

Tenglama standart shaklda.

$$\frac{\pi r^{2}}{3}h=v$$

Ikki tarafini \frac{1}{3}\pi r^{2} ga bo‘ling.

$$\frac{3\times \frac{\pi r^{2}}{3}h}{\pi r^{2}}=\frac{3v}{\pi r^{2}}$$

\frac{1}{3}\pi r^{2} ga bo'lish \frac{1}{3}\pi r^{2} ga ko'paytirishni bekor qiladi.

$$h=\frac{3v}{\pi r^{2}}$$

h uchun yechish

$$\left\{\begin{matrix}h=\frac{3v}{\pi r^{2}}\text{, }&r\neq 0\\h\in \mathrm{R}\text{, }&v=0\text{ and }r=0\end{matrix}\right,$$
