a = π r^{2}

r = \frac{a}{π}, r = - \frac{a}{π}

Solution steps

a = π r^{2}

Switch sides

π r^{2} = a

Divide both sides by

π

r^{2} = \frac{a}{π}

For

x^{2} = f (a)

the solutions are

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

r = \frac{a}{π}, r = - \frac{a}{π}

x, x^{2} + y^{2} + 2 x - 4 y + 5 = 0

\frac{p ^{2} + 21}{7} = 10

0 = x^{2} + 4

\frac{1}{4} x^{2} - x + 1 = 0

5 (x - 2) (x + 1) = 2 x (x + 2) + 20
