Answer:
A) length of the radius of the circle = 15.
Step-by-step explanation:
Given : (x-6)²+(y+5)²=15².
To Find : what is the length of the radius of the circle.
Solution : We have given that (x-6)²+(y+5)²=15².
Standard form of circle (x-h)²+(y- k)²=r².
Where, ( h,k) are vertex point and r = radius .
On comparing (x-6)²+(y+5)²=15² with standard form of circle.
( 6 ,-5 ) are vertex and radius = 15
Therefore, A) length of the radius of the circle = 15.
