Since The square is in a unit circle isn't the radius 1 not 1/2?

Yeah... But I still didnt get it...

Luke, the circle is in a unit square, not the other way around; which means that the diameter is 1, not the radius.

How did we know that the diameter of thé circle is 1?

Ihsane, we know this because the
Circle is right inside a unit square. A unit square has sides equal to 1. Therefore the diameter = 1.

C = q x pie
Then q = 2r because C = 2 x pie x r
r = d / 2 = 1 / 2
q = 2 x 0.5 = 1
Then q = 2r because C = 2 x pie x r
r = d / 2 = 1 / 2
q = 2 x 0.5 = 1

Hi
, I wonder " a is circumscribed about b " means b circumscribe a , is that correct!?

Circumference of a circle = 2πr, where r is the radius. The circle is exactly inside a square. The square is a unit square, which means the sides have length = 1. That means the radius of the circle is 1/2.
So circumference = 2πr= 2*π*1/2 = π
But we are told that circumference = qπ, so q = 1.
