solvefor v= 1/3 pir^2h,r

解答

求解

v = \frac{1}{3} π r^{2} h, r

解答

r = \frac{3 v}{πh}, r = - \frac{3 v}{πh}; h \neq = 0

求解步骤

v = \frac{1}{3} π r^{2} h

交换两边

\frac{1}{3} π r^{2} h = v

在两边乘以

3

πh r^{2} = 3 v

两边除以

πh; h \neq = 0

r^{2} = \frac{3 v}{πh}; h \neq = 0

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

r = \frac{3 v}{πh}, r = - \frac{3 v}{πh}; h \neq = 0

4 x^{2} + 4 x - 48 = 0

abx^2-x(b-2a)=2

ab x^{2} - x (b - 2 a) = 2

2 x^{2} + 3 x = 9

x^{2} - 22 x = 0

(2n-1)x^2+(5n+1)x-3=0

(2 n - 1) x^{2} + (5 n + 1) x - 3 = 0
