\[Дано:\]
\[AC - диаметр;\]
\[AB = 6\ см;\]
\[BC = 12\ см.\]
\[Найти:\]
\[V_{сегментов}.\]
\[Решение.\]
\[1)\ Радиус\ окружности:\]
\[d = AC = AB + BC = 6 + 12 =\]
\[= 18\ см;\]
\[R = \frac{d}{2} = \frac{12}{2} = 9\ см.\]
\[2)\ Объем\ шаровых\ сегментов:\]
\[V_{1} = \pi \bullet AB^{2} \bullet \left( R - \frac{1}{3}\text{AB} \right) =\]
\[= \pi \bullet 6^{2} \bullet \left( 9 - \frac{6}{3} \right) = 36\pi \bullet 7 =\]
\[= 252\pi\ см^{3};\]
\[V_{2} = \pi \bullet BC^{2} \bullet \left( R - \frac{1}{3}\text{BC} \right) =\]
\[= \pi \bullet 12^{2} \bullet \left( 9 - \frac{12}{3} \right) =\]
\[= 144\pi \bullet 720\pi\ см^{3}.\]
\[Ответ:\ \ V_{1} = 252\pi\ см^{3};\ \ \]
\[V_{2} = 720\pi\ см^{3}.\]
