The picture in the attached figure
we know that
The angle bisectors of a triangle intersect in a point (incenter) that is equidistant from the three sides of the triangle
so
ZA=YA=XA-----> <span>are the radii of the inscribed circle
XA=3 cm
therefore
ZA=3 cm
the answer is
ZA=3 cm</span>

Answer:
≈ 11.78 in
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × ( cancel 2π on numerator/ denominator )
= 15 ×
=
≈ 11.78 in ( to 2 dec. places )
