Answer: 10 units.

Step-by-step explanation:

The equation of the circle in Center-radius form is:

(x - h)^2 + (y - k)^2 = r^2

Where the center is (h,k) and "r" is the radius.

The equation of the circle given is:

x ^2 + y^2 = 100

You can observe that is written in Center-radius form.

Then, you can identify that:

r^2=100

Knowing this, you need to solve for "r" to find the lenght of the radius.

This is:

r=\sqrt{100}\\\\r=10

Therefore, the lenght of the radius is 10 units.

<span>We are going to define two equations where b means bagels and m will be muffins, First equation: 10*b + 4*m = 13 Second equation: 5*b + 8*m = 14 From the second equation, we can isolate b: b = (14 - 8*m)/5 In the second equation 10*(14 - 8*m)/5 + 4*m = 13 2*(14 - 8*m) + 4*m = 13 28 - 16*m + 4*m = 13 28 -13 = 16*m - 4*m 15 = 12*m m = 15/12 = 1.25 Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8 So one bagel costs $0.8 and one muffin $1.25</span>
