I am hoping that the a in c = ad is supposed to be x.
The formula for circumference is c = pi * diameter with 3.14 substituting for pi.
Let’s plug in some values
172.7 = 3.14d
Divide
55 = d
The diameter should be 55 cm.
I believe it is A because 3p has to be equal to or greater than 45
First, write an equation
x+7.9= 8.3
Now solve for x.
x=0.4
So first u gotta to 36 divide by 12 so it’s = 3 and now u gotta to 8.90 divide by 3 and it’s = $ 2.96
