Area of a circle is pi*r^2
The center of the circle is the center of the square so the diameter of the circle is 1. This makes the radius 1/2.
Area = pi(1/2)^2 = pi/4 or "e".
Check: the area of the square is 1 so the area of the circle should be less than that. This eliminates "a", "b" and "c" since these are all greater than 1. And the area of a circle must have pi in there somewhere so "e" looks pretty good and pi/4 = 0.785.

The radius of the cirle would have to be 1/2 the side of the square, which is 1/2.
so, Area = pi x radius squared
= pi(1/2)(1/2)
= pi/4
That's answer e)
done

since the diameter of the circle(same as the side of the square) =1
so the radius =1/2
Now the area of a circle =Pi r^2
=Pi.(1/2)^2
=Pi/4 ----(E)

The radius of the inscribed circle is .5
So area = .5^2*pi = pi/4

E=MC2
Where is Eeenergy
M is mass
C is big C
2 is 1+1
so ANswer is pi/4

one of the sides of the square is the diameter of the circle
A = pi r^2
A = pi(1/2)^2
A = pi/4
E

r=1/2 --> Area=pi·(1/2)^2 = pi/4 e)

the diameter is of size 1 too,
so
area = pi/4
Ans: (e)
