Solve for b A=piab

$A = π a b$

Rewrite the equation as $π a b = A$ .

$π a b = A$

Divide each term in $π a b = A$ by $π a$ and simplify.

Divide each term in $π a b = A$ by $π a$ .

$\frac{π a b}{π a} = \frac{A}{π a}$

Simplify the left side.

Cancel the common factor of $π$ .

Cancel the common factor.

$\frac{π a b}{π a} = \frac{A}{π a}$

Rewrite the expression.

$\frac{a b}{a} = \frac{A}{π a}$

Cancel the common factor of $a$ .

Cancel the common factor.

$\frac{a b}{a} = \frac{A}{π a}$

Divide $b$ by $1$ .

$b = \frac{A}{π a}$
