Answer:

$Vol=883.6875\,\, cm^3\\$

Explanation:

Recall that the volume of a whole sphere is given by the formula:

$Vol_(sphere)=(4)/(3) \pi\,R^3$

then, the volume of a semi-sphere would be half of the formula above:

$Vol=(2)/(3)\, \pi\,R^3$

Now, the radius R is given by half of the semi-sphere diameter: 15/2 = 7.5 cm.

which makes our calculation:

$Vol=(2)/(3)\, \pi\,R^3=(2)/(3)\, \pi\,(7.5\,cm)^3=883.6875\,\, cm^3\\$
