πa = \frac{1}{2} π r^{2}

r = 2 a, r = - 2 a

Solution steps

πa = \frac{1}{2} π r^{2}

Switch sides

\frac{1}{2} π r^{2} = πa

Simplify

\frac{1}{2} π : \frac{π}{2}

\frac{π}{2} r^{2} = πa

Multiply both sides by

2

π r^{2} = 2 πa

Divide both sides by

π

r^{2} = 2 a

For

x^{2} = f (a)

the solutions are

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

r = 2 a, r = - 2 a

x^{2} + 3 x = 10

2 (x - 5)^{2} - 64 = 0

s, A = s^{2}

x^{2} + 6 x + 2 = 0

(d + 1) (d - 5) = 2 d^{2} - 7
