Answer:
Area of circle is 7.7cm²
To the nearest tenth
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
