Mathematics

The formula for the area of a circle:
$\pi*r^2$ , where r is radius of circle
$\pi*r^2=19.625|:\pi$
$r^2=\frac{19.625}{\pi}|\sqrt{}$
$r=\sqrt{\frac{19.625}{3.14}}=2.5$
The formula for the circumference of a circle:
$2*\pi*r$ , where r is radius of circle
$2*\pi*r=2*3.14*2.5=15.7$ units squared
As can be seen easily calculated radius of the circle first, and then used this to calculate the circumference of the circle.
