I’m kind of having troublehelp?

c = 13.0

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

c² = 11² + 7² = 121 + 49 = 170 ( take the square root of both sides )

c = ≈ 13.0 ( to the nearest tenth )

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
