Question

I NEED HELP PLZ
What is length of PR
m PZR is 2/3 pie radius

Answer 1

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.
