X - the unknown number
4*x <108
x<108:4
x <22
it depends if x € N, Z or R
for R: x €(-infinite, 22)
for Z: x € {....-4,-3,-2,-1,0,1,...,21}
for N:x €{0,1,2,3,...,20,21}
If an number is an absolute value, it means that the number will be positive. You would plug and check the same way you would for any other equation and it a solution is considered extraneous if the equation is not equal
You would multiply 10 times \pi (3.14)

and get 31.40 cm squared
