Step-by-step explanation:
To find the area of a circle, you need to multiply the square of the radius by pi. To find the radius of a circle, you need to divide the diameter by 2, which in this case is 18/2=9. Now, you can plug it into the formula to find that the area of this circle is 
. Hope this helps!
The expression would be: x+8
The equation would be: x+8=
2nd opinion that’s your answer
