SAT Question a0cacec1: Circles answer and explanation with Desmos solution

The measure of an angle, in degrees, can be found by multiplying its measure, in radians, by $\frac{180\text{degrees}}{\pi \text{radians}}$. Multiplying the given angle measure, $\frac{16\pi }{15}$ radians , by $\frac{180\text{degrees}}{\pi \text{radians}}$ yields $\left(\frac{16\pi }{15}\text{radians}\right)\left(\frac{180\text{degrees}}{\pi radians}\right)$, which simplifies to $192$ degrees.
