Question

Выражение переменных из формул

Answer 1

1)
$s = pi times {r}^{2} \ r = sqrt{ frac{s}{pi} }$
2)
$v = {a}^{2} times h \ a = sqrt{ frac{v}{h} } \h = frac{v}{ {a}^{2} }$
3) Р=2(а+в)
$a = frac{p}{2} - b \ b = frac{p}{2} - a$
4)
$s = frac{ah}{2} \ a = frac{s times 2}{h} \ h = frac{s times 2}{a}$
5)
$v = pi {r}^{2} h \ r = sqrt{ frac{v}{hpi} } \ h = frac{v}{pi {r}^{2} }$
6)
$v = frac{1}{3} pi {r}^{2} h \ r = sqrt{ frac{3v}{hpi} } \ h = frac{3v}{pi {r}^{2} }$

7)
$s = frac{pi {d}^{2} }{4} \ d = sqrt{ frac{s times 4}{pi} }$
8)
$s = frac{abc}{4r} \ r = frac{abc}{s times 4} \ a = frac{s4r}{bc} \ b = frac{s times 4r}{ac} \ c = frac{s times 4r}{ab}$
9)
$s = frac{a + b}{2} times h \ h = frac{2s}{a + b } \ a = frac{s2}{h} - b \ b = frac{2s}{h} - a$
