In a plane, three circles with radius r are constructed with the vertices of a right triangle $ABC$ as centers, and these circles do not intersect each other. The lengths of the parts on the sides of the triangle that are not inside these circles are given as 2 units, 3 units, and 5 units. Accordingly, what is the total area of the regions inside the circles but outside the triangle in square units? A) $6 \pi$ B) $8 \pi$ C) $9 \pi$ D) $\frac { 9 \pi } { 2 }$ E) $\frac { 15 \pi } { 2 }$
