The center of the circle shown below is at (5,4). a point on the circle is at (12,15). what is the radius of this circle? round the answer to the nearest tenth of a unit. a. 10.0 units b. 11.0 units c. 12.0 units d.. 13.0 units

The correct option is D. 13.0 unit

Therefore the Radius of a Circle is 13.0 unit (nearest tenth of a unit)

Step-by-step explanation:

Given:

Let C be the center of a Circle

C = (x₁ , y₁) = ( 5 , 4)

Let A be the point on a Circle

A = (x₂ , y₂) = ( 12 , 15)

To Find:

Radius, CA = ?

Solution:

Radius :

The radius of a circle is the distance from the center of the circle to any point on its Circle.

So By Distance Formula Between Two point is given as

Substituting the values we get

Therefore the Radius of a Circle is 13.0 unit

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
