The length of XPY can be found using the Pythagorean Theorem:
XP² + PY² = XY²
Plugging in the given values:
(6π)² + (16π)² = XY²
36π² + 256π² = XY²
292π² = XY²
Taking the square root of both sides:
XY = √(292π²)
XY = 2π√73
Since XPY is half of the circle with radius XY, its length is:
XPY = (1/2)(2πr) = πr
Plugging in the value of XY:
XPY = π(2π√73)
XPY = 2π²√73
Therefore, the length of XPY in terms of π is 2π²√73, which is closest to choice a) 192π m.
