The circle equation is in the format (x – h)2 + (y – k)2= r2, with the center being at the point (h, k) and the radius being "r".
Therefore (x – 1)2 + (y +5)2= 102
x2 + y2 + 1 - 2x + 25 + 10y = 100
x2 + y2 - 2x + 10y = 74
Answer:
r=21
Step-by-step explanation:
r-15=6
r=6+15
r=21
Answer:
4.9 (rounded)
Step-by-step explanation:
