Answer: square of radius or [tex]r^2[/tex]
Step-by-step explanation:
We know that a circle is a geometric shape that consist all points that are equidistant from a particular point known as centre.
The distance from center and any point on the boundary of circle is known as radius.
The formula to find the area of the circle is given by :_
[tex]\text{Area}=\pi r^2[/tex] , where r is the radius.
Therefore , in the formula for the area of a circle, [tex]r^2[/tex] gets multiply by [tex]\pi[/tex].
