A point is in a circle if the distance from the center of the circle to the point is equal to the
2 answers:
Answer with explanation:
It is given that point is on the circle.
⇒Distance from any point on the circle to center of the circle =Radius of that Circle
Also, we can Prove the Result with the help of Definition of Circle which states that, A Circle is Locus of all the points such that Distance from a fixed point Called center to all these points is always Constant. And when you join all these points the shape you will get is in the shape of Circle.
The Length of Radius is fixed, and in a circle there are infinite number of Radii.
Option C: Radius

Answer:
D
Step-by-step explanation:
So we have the equation:
And we want to solve for x.
We can solve it by completing the square.
First, subtract 58 from both sides:
Divide the b term by 2 and square it:
So, add 9 to both sides:
On the left, the perfect square trinomial pattern. Add on the right. So:
Take the square root of both sides:
The square root of -49 is 7i:
Add 3 to both sides:
So, our answer is D.
And we're done!
