Solve for r A=pir^2

solve for

r, A = p i r^{2}

No Solution

Solution steps

A = p i r^{2}

Substitute

r = x + y i

A = p i (x + y i)^{2}

Expand

p i (x + y i)^{2} : - 2 p x y + i p (x^{2} - y^{2})

A = - 2 p x y + i p (x^{2} - y^{2})

Rewrite

A

in standard complex form:

A + 0 i

A + 0 i = - 2 p x y + i p (x^{2} - y^{2})

Complex numbers can be equal only if their real and imaginary parts are equalRewrite as system of equations:

[A = - 2 p x y 0 = p x^{2} - p y^{2}]

[A = - 2 p x y 0 = p x^{2} - p y^{2}] : No Solution

Substitute back

r = x + y i

No Solution

x^{3} - 9

A, b 2 A = \frac{1}{2} h (b_{1} + b_{2})

x, e^{l n (x^{2})} - 16 = 0

r, V = \frac{1}{3 p i r ^{2} h}

t, - lo g_{10} (12) = - (\frac{( lo g _{10} ( 2 ) )}{5.1}) t
