-2(2x+9)>-4x+9
1)We solve this inequation:
-2(2x+9)>-4x+9
-4x-18>-4x+9
-4x+4x-18>9
-18>9 This is not true, because -18<9; Therefore this inequation is never true.
Answer: this inequation is never true.
Using 3.14 as an estimate for pi, the answer is 3037.95 in. cubed. But if more digits of pi were used, the answer is 3039.49 in. cubed. I found the answer by using the sphere volume formula (4/3) on both sphere measurements, then subtracted the smaller core sphere from the rest of the sphere. The above named numbers were the result.
