Question

The square of radius of a circle is 3. What is its area?​

Answer 1

Answer:

3π is the area of cicle . put value of π as suggested in question.

Answer 2

Concept:

The circle is the locus of any variable point from its fixed distance. The distance from origin to any point of the circle is called radius.

Given:

Here we have given that square of radius of circle is 3

that is $r^{2} =3$

Find:

We are ask to calculate the area of that circle

Solution:

The formula for area of the circle whose radius r is given by

Area  = $\pi r^{2}$

As per given put the value of $r^{2} =3$

Therefore

Area = $3\pi$

If we put the value of $\pi$ = 3.14

The area will be = 9.42 square unit.

Hence the final answer is 9.42
