Which equation represents a circle with the same center as
the circle shown but with a radius of 2 units?
O (x - 4)2 + (y – 5)2 = 2
O (x - 4)2 + (y – 5)2 = 4
O (X - 5)2 + (y - 4)2 = 2
O (X - 5)2 + (y - 4)2 = 4

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
