So I use the formula hopefully these steps work
I hope that 2-1 means 21.
DE + EF = DF
4x + 10 + 21 = 9x - 15
4x + 31 = 9x - 15
31 = 9x - 4x - 15
31 = 5x - 15
46 = 5x
x = 9 1/5 = 9.2
You want 9x - 15
9*9.2 - 15
82.8 - 15
67.8 <<<<< answer.
If I have given the wrong meaning to 2-1 (which could mean 1) leave another note and I will correct my work.
Circumference = 2*pi*radius
find the radius using this formula.
then use this formula => area of circle = pi*radius*radius
put the value of the radius that you get with the first formula to find the area
hope it helps you
