5 is you median
4 is your mean
8x = 54 - 6.
Then lets solve the equation. :)
8x = 48.
x = 6.
Hope it helps! :)
Answer:
Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715
