An equation is given.

7x+2=5x+8

what value of x makes the equation true?

To make the equation true, the value of x would be 3.

Area=pi times radius squared or a=pi times r^2

diameter=2r
diameter=18
radius=1/2diameter
radius=1/2(18)=9

area=pi times 9^2
area=pi times 81
81π feet squared is the answer

aprox pi=π to 3.14 and do
81 times 3.14=254.34
the answer is closest to 254.34 square ft
