‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️‼️ ! i’ve been waiting for 30 minutes and still no one has ! only answer if you absolutely know you have the correct answer! explain how you got your answer! you so much

PART ;

Circle A
Circumference - 2 pi r
25.12 = 2pi(4)
25.12 = 8i
Divide both sides by 8!!
3.14=pi

...Circle B
Circumference = 2 pi r
9.42 = 2pi(3/2)
9.42 = 3pi
Divide both sides by 3!!!
3.14 = pi

PART B

Circle A
A=pi r ^2
50.24 = pi(4)^2
50.24=16pi
Divide both sides by 16!!!
3.14=pi

Circle B
A=pi r^2
7.065=pi(3/2)^2
7.065= 9pi/4
Divide both sides by 9/4!!!
3.14=pi

PART C

They used exactly 3.14 for the value of pi in CIRCLE A and B to get the circumference and the area :D

I hope this makes sense!!! 
When I wrote 'pi', it was supposed to be the symbol for pi.
