Final answer:

The volume of water in the bowl as a function of h is (2/3)π(2h - h²).

Step-by-step explanation:

The volume V of the hemispherical bowl can be calculated using the formula for the volume of a hemisphere, which is given by

V = (2/3)πr³, where r is the radius of the hemisphere.

In this case, the radius is 5 inches.

Therefore, the volume of the hemispherical bowl filled to a depth of h inches is given by

V = (2/3)π(5² - (5-h)²)

= (2/3)π(25 - (25 - 2h + h²))

= (2/3)π(2h - h²).

The special cases where h = 0 and h = 5 can be checked:

When h = 0, the volume of water in the bowl is V = (2/3)π(2(0) - (0)²) = 0.

When h = 5, the volume of water in the bowl is V = (2/3)π(2(5) - (5)²)

= (2/3)π(10 - 25)

= 10π.
