Question

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

Answer 1

Answer:

Option (4)

Step-by-step explanation:

m(∠PZR) = $\frac{2}{3}\pi$

Radius of the circle = 8

Since, length of an arc = $\frac{\theta}{2\pi }(2\pi r)$

Here, θ = Central angle in radians

From the given formula,

m(arc PR) = $\frac{\frac{2}{3}\pi}{2\pi }(2\pi \times 8)$

                = $\frac{2}{6}(16\pi )$

                = $\frac{16}{3}\pi$

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