First, we need to find the radius and height of the cylinder. Since the volume of the cylinder is 36 cm^3, we can use the formula for the volume of a cylinder:

V = πr^2h

36 = πr^2h

Since the height of the cylinder is equal to the diameter of the sphere, we have h = 2r. Substituting this into the equation gives us:

36 = πr^2(2r)

36 = 2πr^3

r^3 = 18/π

r = (18/π)^(1/3)

Now that we have the radius of the cylinder, we can find the volume of the sphere using the formula for the volume of a sphere:

V = (4/3)πr^3

Substituting r = (18/π)^(1/3) into the equation gives us:

V = (4/3)π((18/π)^(1/3))^3

V = (4/3)π(18/π)

V = 24 cm^3

Therefore, the volume of the sphere is 24 cm^3.

So, the correct answer is:
24 cm^3
