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.
It would be C because that is the one that make the most sense
Answer:
JM is the diameter or 180°
MK = diameter - 21° = 159°
Step-by-step explanation:
9/100, let me know if this helps.
<span> In math, we have a formula that relates these two parts of a circle. This formula is called the </span>circumference<span> formula, and it is C = pi*d where C stands for the </span>circumference<span> and d stands for the </span>diameter<span>. And pi is pi or 3.14.</span>
