Help I need this rn! And please explain

Answer:

(4, 0)

Step-by-step explanation:

The circumference of a circle is $2 \pi r$ where r is the radius.

In this case, $2 \pi r = 10 \pi$ . Divide both sides of the equation by $2\pi$ to get

$r=5$

The center of the circle is on the x-axis, so the intercepts are 5 units to the left of the center and 5 units to the right of the center. The two intercepts are (-1-5, 0) and (-1+5, 0). The point that is on the positive x-axis is (4, 0).
