Question

Does anyone know it?

Answer 1

4π/5

Explanation:

APC angle is equals to AC arcle.

The inscribed angle is 2π/5. To discover an inscribed angle, the formula is:

IA = IC/2

IA = inscribed angle

IC = central angle

IA = 2π/5

`(2\pi)/(5) = (IC)/(2) \\\\\ 5IC = 4\pi \\\ IC = (4\pi)/(5)`

IC angle = AC arcle

AC = 4π/5
