XPY is the circumference minus XY

the angle of arc XY is 90 degrees

a full revolution of a circle is 360 degrees

the distance XY is 1/4 of the circumference of the circle

the circumference of a circle is C=2 pi r

r is 10m

the circumference is 20 pi

1/4 of 20 is 5

the distance of arc XY is 5 pi

20pi - 5 pi = 15 pi
