Question

What is the radius pf a circle whose equation is (x+5)^2+(y-3)^2=4^2

Answer 1

The answer is 5. Hope this helped you. My brother had to help me on this. How was your day.

Answer 2

we know that

the equation of the circle is of the form

(x-h)^2+(y-k)^2=r^2

where

(h,k) is the center of the circle

r is the radius of the circle

in this problem we have

(x+5)^2+(y-k)^2=r^2

so

the center is the point (-5,3)

the radius is 4 units

therefore

the answer is

The radius of the circle is equal to 4 units
