Its 95
Tens = 90
Ones = 5
90 + 5 = 95
2x = 2 * 3 = 6
6^2 = 6*6 = 36
36 + 3 = 39
Answer: 39
I honestly think its around 250000 because 11,000 that he got for submitting and then the other cost takes the 11,000out so that leaves the 250,000 but I'm about 95% sure and the take 0.4 out of the total.
The formula can also be proved using a trigonometric substitution . Each of above proofs will generalize to show that the volume of an ellipsoid with semi-axes A, B and C is just
(4/3)*Pi*A*B*C
