Answer:
39.26 in
Step-by-step explanation:
This problem, bothers on the mensuration of flat shapes.
we know that the perimeter of a circle is the same as the cirmcumference
we also know that the circumference is given as
C= 2πr
For circle A
C=2*3.124*2
C= 12.56 in
For circle B
C=2*3.124* 3 1/4
C= 2*3.142*13/4
C= 2*3.142*3.25
C= 20.42 in
For circle C
C=2*3.124*1
C= 6.284 in
Now the perimeter of all the circles ABC is
=12.56 +20.42 + 6.284
=39.26 in
