I might be able to help. Let's see them?
OpenStudy (anonymous):
what the length of the indicated arc? the radius is 3 and the degrees is 90 A. (3/4)PI B. 3PI/2 C.3PI D. 4PI E. NONE OF THE ABOVE
OpenStudy (mathmale):
First of all, be certain that you know the arc length formula: \[arc~length=s=r*\theta, \] where r is your radius and theta is the "central angle" in radians (not in degrees).
