Answer:
the mean
Step-by-step explanation:
mean is calculated average
Move 12 to the other side, making it negative
h=31-12
h=19
I believe that when finding the radius of a circle you half the diameter, but when finding the circumference of a circle you need to multiply the diameter (14cm) by pi.
So 14xpi= 43.98229715
But it can be simplified/ rounded to 44cm.
Of course I might be incorrect so do please correct me if I am wrong.
Are you trying to solve for c? if so c=8
