A balloon is a sphere and the volume of a sphere is V=4/3 π.R³
V= 4/3.π.(6³) = 4/3.π.216 = 288π unit³ or ≈ 905 unit³
19.2 because the 0.09 changes the 0.1 to a 0.2
First, add 29 on both sides.
42 - x is less than or equal to 0.
Next, add x on both sides.
42 is less than or equal to x.
Hence, the correct answer is (C).
