r^{2} = 80

r = 45, r = - 45

Decimal Notation

r = 8.94427 \dots, r = - 8.94427 \dots

Solution steps

r^{2} = 80

For

x^{2} = f (a)

the solutions are

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

r = 80, r = - 80

80 = 45

- 80 = - 45

r = 45, r = - 45

a^{2} - 3 a - 1 = 6

x, z = x^{2} + 4 y^{2}

x, y = x^{2} - 3 x + 2

\frac{1}{2} x^{2} - 5 = 5

r, S = 2 π r h + 2 π r^{2}
