Answer:

Area of circle is 7.7cm²

To the nearest tenth

Step-by-step explanation:

This problem has some missing details as regarding the unit of the side of the square "n"

Assuming that the side n is in cm

n=3.14cm

Since the circle fits perfectly into the square, it means the diameter of the circle is same as the side of the square

Hence diameter d=n= 3.14cm

Therefore radius r=d/2= 3.14/2

r=1.57cm

π= 3.142

We know that the area of a circle is

A=πr²

Substituting our radius we have

A= 3.142*1.57²

A=3.142*2.4649

A=7.744cm²

Rounding to the nearest tenth

Area of circle is 7.7cm²
