127,796,483=3.14r^2

Solution for 127,796,483=3.14r^2 equation:

127.796.483=3.14r^2

We move all terms to the left:

127.796.483-(3.14r^2)=0

We add all the numbers together, and all the variables

-(3.14r^2)+61.725468=0

We get rid of parentheses

-3.14r^2+61.725468=0

a = -3.14; b = 0; c = +61.725468;
Δ = b2-4ac
Δ = 02-4·(-3.14)·61.725468
Δ = 775.27187808
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$r_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$r_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$r_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{775.27187808}}{2*-3.14}=\frac{0-\sqrt{775.27187808}}{-6.28}
=-\frac{\sqrt{}}{-6.28}
$
$r_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{775.27187808}}{2*-3.14}=\frac{0+\sqrt{775.27187808}}{-6.28}
=\frac{\sqrt{}}{-6.28}
