A circle with center (-3,5) passes through point (-9,-3). Find the circumference of the circle

Aliun [14]

Answer:20π

Step-by-step explanation:

equation of the circle

(x+3)² + (y-5)² = r²

now, (-9, -3) lies on it

So, (-9+3)² + (-3-5)² =r²

36+ 64 = r² =100

hence, r =10

So, circumference = 2πr = 20π
