The volume of a cone is given by the formula V = (1/3)πr^2h, where r is the radius and h is the height.
Given that the volume of the cone is (25/3)π cm^3, we can set up the equation as follows:

(25/3)π = (1/3)πr^2h

Given that the height of the cone is equal to the sphere's diameter, we can substitute h with 2r, where r is the radius of the sphere.

(25/3)π = (1/3)πr^2(2r)

Simplifying the equation, we get:

25 = 2r^3

Dividing both sides by 2, we have:

12.5 = r^3

Taking the cube root of both sides, we find:

r = 2.5

Now, let's find the volume of the sphere using the formula V = (4/3)πr^3, where r is the radius.

V = (4/3)π(2.5)^3
V = (4/3)π(15.625)
V = 62.5π/3

So, the volume of the sphere is 62.5π/3 cm^3, which is equivalent to around 65.45 cm^3.

Therefore, the correct answer is not provided.

I apologize for the confusion. Let's recheck the calculations.

We are given that the volume of the cone is (25/3)π cm^3. Using the formula for the volume of a cone, V = (1/3)πr^2h, and substituting the given volume, we have:

(25/3)π = (1/3)πr^2h

Since the height of the cone is equal to the sphere's diameter, we can substitute h with 2r, where r is the radius of both the cone and the sphere:

(25/3)π = (1/3)πr^2(2r)

Simplifying further, we get:

25/3 = 2r^3

Multiplying both sides by 3/2, we have:

r^3 = (25/2)

Taking the cube root of both sides, we find:

r = (25/2)^(1/3)

Now, let's find the volume of the sphere using the formula V = (4/3)πr^3, where r is the radius:

V = (4/3)π((25/2)^(1/3))^3

Simplifying the expression, we get:

V = (4/3)π(25/2)

V = (100/6)π

So, the correct answer is (O) 50/3 π cm^3. I apologize for the confusion earlier.
