Use the relationship among the formulas for the volumes of cones, cylinders, and spheres to solve the following problem. The volume of a cylinder is 36 cm3. What is the volume of a sphere if its radius is the same as the cylinder’s and the height of the cylinder is equal to the sphere’s diameter?(1 point)

The volume of a cylinder is given by V = πr^2h, where r is the radius and h is the height.
Given that the volume of the cylinder is 36 cm^3, we can write:
36 = πr^2h
Additionally, the height of the cylinder is equal to the sphere's diameter, so h = 2r.
Substitute h = 2r into the equation:
36 = πr^2(2r)
36 = 2πr^3
r^3 = 18/π
r = (18/π)^(1/3)
Now, the volume of a sphere is given by V = (4/3)πr^3.
Substitute r = (18/π)^(1/3) into the equation:
V = (4/3)π(18/π)
V = 24 cm^3
