If each side of the square below is 8 inches, the probability that a point chosen at random in the square is in the blue region would be 0.25.
25.5 es eso creo perdón si esta mal
<span>0.5p - 3.45 = -1.2 ⇒ p=4.5</span>
Since we have that the volume of a sphere is given by:

And we have that the diameter equals 3.6ft, we then will have a volume of:

Since we have that the volume is approximately 13.74 ft^3, then the best approximation in the problem is A. 13.6 ft^3.
