HEL ME GUY 1. Find the equation of the circle whose center and radius are given.

center ( -2, -5), radius = 1

2. Find the equation of the circle whose center and radius are given.

center ( 7, -3), radius = sqr7

Step-by-step explanation:

we are given the center and the redious of a circle equation

remember that,

where (h,k) is the centre coordinate and r is redious of the circle

given that, h=-2 , k=-5 and r=1

Thus substitute:

simplify:

Likewise

given that,h=7,k=-3 and r=√7

substitute:

simplify:
