Answer:
17pi/15
Step-by-step explanation:
s = r *theta where r is the radius and theta is the central angle in radians
Convert 51 to radians
51 * pi/180 = 51pi/180
s = 4 * 51pi/180
= 17pi/15
Answer:
Step-by-step explanation:
The standard form of a circle's equation is
where h and k are the circle's center and r is the radius. We are told, and we can see, that the center of the circle is (0, 0) so h = 0 and k = 0. The radius, given as 4, goes into the equation squared, so the equation is
which simplifies down to
, choice C.
