if the radius of Circle A is 2 inches the radius of circle B is 3 1/4 inches and the radius of circle C is 1 inch what is the perimeter of ABC
 
											 
											Answer: The perimeter of triangle ABC is 12 1/2 inches.
Step-by-step explanation: Each radius given is used twice in the diagram to connect to the radii of the adjacent circles to form the sides of the triangle.
So the perimeter of the triangle is found by adding twice the length of each radius.
P= 2( 2 + 3 1/4 + 1)
P= 2( 6 1/4)
P = 12 1/2
