V = s^3= 343 = 7×7×7
S = 7 cm
The question is asking you to find the measure of YZ's arc.
The arc of a circle is found by finding the central angle. In this case, that's angle YCZ. Remember that a circle's total degrees is 360. Since the angle that you are trying to find is 16% of the circle, you need to find 16% of 360.
360*0.16 = 57.6
The measure of arc YZ is 57.6 degrees.
I assume you need find out √28=√7*4=2√7
√150=√5*5*6=5√6
hope it helps
