Hi there! The answer is ( - 7, 5)
The standard form of the equation of a circle is the following:
In this equation r represents the radius of the circle and the point (a, b) is its centre.
Therefore, the centre of the circle
is the point ( - 7, 5).

The length of the support cable is about 29 feet.
If you sketch out the question, you will see that it will form a right triangle with the cable as the hypotenuse.
Just set up and use the Pythagorean Theorem.
15^2 + 25^2 = c^2
850 = c^2
29.15 = c
A circle is 360° all the way around; therefore, if you divide an arc's<span> degree </span>measure<span> by 360°, you </span>find<span> the fraction of the circle's circumference that the </span>arc<span> makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you </span>get<span> the length along the </span>arc<span>.</span>
