Question

Area(A) of a circle is directly proportional to the square of its radius(r) the given statement can be written using symbol of variation

Answer 1

A = area of a circle
r = radius of the circle
there for
A variation r^2

Answer 2

Answer:

Area (A)  ∝ $r^2$.

Step-by-step explanation:

Explanation:

Given that, the area (A) of a circle is directly proportional to the square of its radius(r).

• Circle - All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.

• And we know that the radius of a circle is the separation between any two points on its circumference. R or r is typically used to indicate it.

Area of a circle = $\pi r^2$

According to the question area of a circle is directly proportional to the square of its radius(r).

⇒ Area (A)  ∝ $r^2$.

Final answer:

Hence, according to the given statement,  Area (A)  ∝ $r^2$.
