Answer:

JM ≈ 12.9 miles

Step-by-step explanation:

The length of the arc is calculated as

arc = circumference × fraction of circle

= πd × $\frac{90}{360}$

JM = π × 16.4 × $\frac{1}{4}$

= $\frac{16.4\pi }{4}$ ≈ 12.9

Write the equation of the circle passing through the origin with center (– 9, –12) .

malfutka [58]

Answer:

$(x+9)^{2} +(y+12)^{2}=225$

Step-by-step explanation:

Remember that the center of a circle is written in (h,k) format. So h= - 9 and k = -12. Also, the distance between those two points is 15 units, so r = 15.

So the formula $(x-h)^{2} +(y-k)^{2}=r^{2}$

Should look like $(x+9)^{2} +(y+12)^{2}=225$
