What is the radius of a circle whose equation is x2 + y2 – 10x + 6y + 18 = 0? units

15

Step-by-step explanation:

 The radius of the given circle is 4 units.

Step-by-step explanation:  We are given to find the radius of the circle with the following equation :

We know that

the standard equation of a circle with center at the point (h, k) and radius r units is given by

From equation (i), we have

Comparing it with the standard equation, the radius of the circle is given by

Thus, the radius of the given circle is 4 units.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

i believe the answer is the polygon, heptagon.
