Standard form of a circle" (x-h)²+(y-k)²=r², (h,k) being the center, r being the radius.
in this case, h=-2, k=6, (x+2)²+(y-6)²=r²
use the point (-2,10) to find r: (-2+2)²+(10-6)²=r², r=4
so the equation of the circle is: (x+2)²+(y-6)²=4²
Answer:
B) 38.4
Step-by-step explanation:
Answer:
Step-by-step explanation:
√((5-1)²+ (4 - (-6))²
√(4)² + (10)²
√(16+100)
√116
2√(29)
