a=3.14xr^2

a = 3.14 x r^{2}

x = \frac{50 a}{157 r ^{2}}; r \neq = 0

Solution steps

a = 3.14 x r^{2}

Switch sides

3.14 x r^{2} = a

Multiply both sides by

100

314 r^{2} x = a \cdot 100

Divide both sides by

314 r^{2}; r \neq = 0

x = \frac{50 a}{157 r ^{2}}; r \neq = 0

x = \frac{( 2 - 3 )}{( 2 + 3 )}

2 h + r = 35

x, p (x) = y^{2} + y^{4} - y^{6}

x, \frac{1}{z} \cdot x = 12

(7.2) y = - 2
