expand (pih^2(3r-h))/3

expand

\frac{π h ^{2} ( 3 r - h )}{3}

π h^{2} r - \frac{π h ^{3}}{3}

Solution steps

\frac{π h ^{2} ( 3 r - h )}{3}

Expand

π h^{2} (3 r - h) : 3 π h^{2} r - π h^{3}

= \frac{3 π h ^{2} r - π h ^{3}}{3}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{3 π h ^{2} r - π h ^{3}}{3} = \frac{3 π h ^{2} r}{3} - \frac{π h ^{3}}{3}

= \frac{3 π h ^{2} r}{3} - \frac{π h ^{3}}{3}

Divide the numbers:

\frac{3}{3} = 1

= π h^{2} r - \frac{π h ^{3}}{3}

- 2.5 (25 x^{2} + 361)^{\frac{1}{2}} + 25 (x + 2.5)

\frac{1}{6} n (n + 1) (2 n + 1)

- \frac{1}{( x + 4 ) ^{2}}

(x + x) \cdot (x)

\frac{- x + 2 + ( x + 1 ) x - 2}{x + 1}
