Answer: The diameter is 12.
Step-by-step explanation:
We know that the circumference can be found by the following formula:
C= Dπ or C= 2rπ I recommend using the one with the variable "D" , it is easier
Because we know that the circumference is 37.68 inches, we can substitute that for the variable "C" and solve for D, the diameter.
(37.68) = Dπ Divide by 3.14, as the instructions in this question specify to do so.
37.68/3.14 = D π/ 3.14
D = 12 The diameter equals twelve.
