Answer:

1150in^3 is close

Step-by-step explanation:

We'll be using the formula for volume of a sphere.

We need the radius - but it's just half the diameter, so r = d/2 = 13in / 2 = 6.5in

$V = \frac{4}{3}\pi r^2\\~\\V = \frac{4}{3}\pi \cdot (6.5in)^3 = \frac{4}{3}\pi \cdot 274.625in^3 = \pi \cdot 366.16666...~ in^3 \approx 1150.34650999 in^3\\$
