Answer:

Option (4)

Explanation:

m(∠PZR) =
(2)/(3)\pi

Radius of the circle = 8

Since, length of an arc =
(\theta)/(2\pi )(2\pi r)

Here, θ = Central angle in radians

From the given formula,

m(arc PR) =
((2)/(3)\pi)/(2\pi )(2\pi * 8)

=
(2)/(6)(16\pi )

=
(16)/(3)\pi

Therefore, Option (4) will be the correct option.
