Answer:

The formula for the volume of a hemisphere is V = (2/3)πr³. Solving for r, we get r = (3V/4π)^(1/3). Substituting V = 2507 in³, we get r ≈ 7.5 in. The diameter of a hemisphere is twice its radius, so the diameter of this hemisphere is approximately 15 inches to the nearest tenth of an inch.

The volume of a hemisphere is given by the formula:

V = (2/3)πr^3

where V is the volume and r is the radius.

We are given that the volume of the hemisphere is 2507 in^3, so we can set up the equation:

(2/3)πr^3 = 2507

Solving for r, we get:

r^3 = (2507 × 3) / (2π) = 3764.51

Taking the cube root of both sides, we get:

r = 15.67

The diameter of the hemisphere is twice the radius, so:

d = 2r = 31.34

Rounding to the nearest tenth of an inch, we get:
