C = 5/9(F - 32)...multiply both sides by 9/5, eliminating the 5/9 on the right
9/5C = F - 32...add 32 to both sides
9/5C + 32 = F <===
To get the circumference you times 3.14 which is PI and times PI by diameter to get the circumference
Sounds as tho' something's missing here. What is "the average" You haven't given it.
If "the average" were 5, then 1 is 4 units below the average, 4 is 1 unit below the average, and 6 is 1 unit above the average.
Check the original problem. Isn't the average given there?
X*26=180
180-26=180
x=154 degrees
