# You are given a circle B whose center is (4, 3) and a point on (10, 3) and another circle C whose center is (-3, -5) and a point on that circle is (1,-5). What is the ratio of circle B to circle C?

#### Explanation:

#"we require to calculate the radii of the circles and compare "#

#"the radius is the distance from the centre to the point "#

#"on the circle"#

#" centre of B "=(4,3)" and point is "=(10,3)#

#"since the y-coordinates are both 3, then the radius is "#

#"the difference in the x-coordinates"#

#rArr" radius of B "=10-4=6#

#"centre of C " =(-3,-5)" and point is "=(1,-5)#

#"y-coordinates are both - 5"#

#rArr"radius of C" =1-(-3)=4#

#"ratio "=(color(red)"radius_B")/(color(red)"radius_C") =6/4=3/2=3:2#
