скриншот условия
440. Тело R состоит из тел Р и Q, имеющих соответственно объёмы V₁ и V₂. Выразите объём V тела R через V₁ и V₂, если:
а) тела Р и Q не имеют общих внутренних точек;
б) тела Р и Q имеют общую часть, объём которой равен V₁.
Решение 2. №440 (с. 120)
Решение 3. №440 (с. 120)
Решение 4. №440 (с. 120)
Решение 6. №440 (с. 120)
а) По условию, тело R является объединением тел P и Q. Мы должны выразить объем $V$ тела R через объемы $V_1$ (тело P) и $V_2$ (тело Q).
В этом пункте сказано, что тела P и Q не имеют общих внутренних точек. Это означает, что объемы этих тел не пересекаются (объем их пересечения равен нулю). Следовательно, объем составного тела R равен простой сумме объемов его частей.
Формула для нахождения общего объема $V$ будет:
$V = V_1 + V_2$
Ответ: $V = V_1 + V_2$
б) В данном случае тела P и Q имеют общую часть, объем которой равен $\frac{1}{3}V_1$. Это означает, что тела пересекаются.
Чтобы найти объем объединения двух пересекающихся тел, необходимо сложить их индивидуальные объемы и вычесть объем их общей части (пересечения), так как в противном случае эта общая часть была бы учтена дважды. Это следует из принципа включений-исключений.
Общая формула для объема объединения $V(P \cup Q)$ выглядит так:
$V = V(P) + V(Q) - V(P \cap Q)$
Подставим в формулу известные нам значения: $V(P) = V_1$, $V(Q) = V_2$ и объем пересечения $V(P \cap Q) = \frac{1}{3}V_1$.
$V = V_1 + V_2 - \frac{1}{3}V_1$
Теперь сгруппируем слагаемые с $V_1$ и упростим выражение:
$V = (1 \cdot V_1 - \frac{1}{3}V_1) + V_2 = (1 - \frac{1}{3})V_1 + V_2 = \frac{2}{3}V_1 + V_2$
Ответ: $V = \frac{2}{3}V_1 + V_2$
