Question

The area (A) of the circle is proportional to square of its radius(r). The given statement is written in mathematical form as________.

Answer 1

Answer:

Area of square = area circle is proportional to each other

Answer 2

The area (A) of the circle is proportional to square of its radius(r). The given statement is written in mathematical form as $A\propto r^{2}$.

Explanation:

Area of circle  can be given by formula:

$A=\pi\ r^{2}$

Where

A= Area of  circle.

r = radius of circle

In  formula, the area A of the circle is proportional to square of its radius r and the same can be denoted as $A\propto r^{2}$.Thus,

Thus,the area (A) of the circle is proportional to square of its radius(r). The given statement is written in mathematical form as $A\propto r^{2}$.
