9pi approximately 28
Step-by-step explanation:
we have the formula - pi r^2

the radius is 3 so then we have pi 3^2
which becomes 9pi which is about 28.2 
rounding to 28

Solve the absolute value equation.
First subtract 5 from both sides.
|x|+5=18
|x|=13
If the absolute value of x is 13 that x equals 13 and -13. Absolute value means distance from 0.
x=13,-13
