I don't know if I'm over thinking this problem but I just want to make sure.

g/cm^3

Step-by-step explanation:

mass(g)/v(cm^3)

the answer should come out as g/cm^3, since mass and v are technically constants

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
