Answer 1

Answer:

r = 5.63 cm

Step-by-step explanation:

Given that,

The area of a circle, A = 99.88 cm²

We need to find the radius of the circle. We know that, the area of a circle is given by :

$A=\pi r^2\\\\r=\sqrt{\dfrac{A}{\pi}} \\\\r=\sqrt{\dfrac{99.88}{\pi}} \\\\r=5.63\ cm$

So, the radius of circle is 5.63 cm.
