For each circle equation shown below state the coordinates of its center and the length of its radius.
1.) x^2 +y^2=16
2.) (x-8)^2+(y+3)^2=100
3.) (x+2)^2 + (y+7)^2=49
4.) (x-6)^2 +y^2=1
5.) x^ +y^2= 25
6.) (x-3)^2+(y-8)^2=64

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

idk

step-by-step explanation:

i think the answer is 90 hope this
