Answer:

(x+5)^2+(y-8)^2=81

Step-by-step explanation:

General equation of a circle is (x-a)^2+(y-b)^2=r^2.

Center coordinates = (-5, 8)

a = -5           b = 8          r = 9

\\(x+5)^2+(y-8)^2=9^2

(x+5)^2+(y-8)^2=81

Answer:

Approximately 439.6 square millimeters.

Step-by-step explanation:

The formula for the surface area of a cone is the following:

A=\pi r^2+\pi r l

Where, <em>r </em>is the radius and <em>l</em> is the slant height.

The radius is 7 and the slant height is 13. We also use 3.14 for π Thus:

A=(3.14)(7)^2+(3.14)(7)(13)\\\text{Use a Calculator}\\A\approx 439.6

Kara and Steven are biking around a 1,800 kilometer path. They start biking from the same place, at the same time, and in the sa
levacccp [35]
It would take them 120 hours to get to the same point on the path again.

Kara is traveling at half the speed of Steven. Therefore, we Steven finishes his second lap Kara will just be finishing her first lap. They will both be at the starting lap again.

It will take Kara 120 hours to complete the lap. 
1800 / 15 = 120  

(That is a lot of time, do you have the numbers correct?)
