Create a function to determine whether or not two circles are colliding. You will be given the position of both circles in addition to their radii:

function collision(x1, y1, radius1, x2, y2, radius2) {
  // collision?
}

bool IsCollision(float x1, float y1, float r1, float x2, float y2, float r2)
  // collision?
}

def collision(x1, y1, radius1, x2, y2, radius2):  
  # collision?

If a collision is detected, return true. If not, return false.

Here's a geometric diagram of what the circles passed in represent:
