In a word, yes.
22" is the radius of the circle.
A 90* arc follows the edge of a circle and takes up the horizontal space of the radius. But the straight-line distance from one end of that arc to the other is...
a2 + b2 = c2
222 + 222 = c2
484 + 484 = c2
968 = c2
~31.11"
Where a and b are the radius of the circle and c is the hypotenuse, or the distance between the two points.
