the volume of a sphere is 48 m^3. what is the volume of a cylinder if its radius is the same as the sphere's and its height is equal to the sphere's diameter

1 answer

The volume of a sphere is given by the formula:

V_sphere = (4/3)πr^3

where r is the radius of the sphere.

Since the volume of the sphere is 48 m^3, we can set up the equation:

48 = (4/3)πr^3

To find the radius, we can solve this equation for r:

r^3 = (3/4) * (48/π)

r^3 ≈ 18.85

Taking the cube root of both sides, we find:

r ≈ 2.74

Now, let's find the diameter of the sphere. The diameter is twice the radius:

d = 2r ≈ 5.48

The height of the cylinder is equal to the sphere's diameter, so h = d ≈ 5.48.

The volume of a cylinder is given by the formula:

V_cylinder = πr^2h

Substituting the values we found:

V_cylinder = π * (2.74)^2 * 5.48

Simplifying, we find:

V_cylinder ≈ 214.07 m^3

Therefore, the volume of the cylinder is approximately 214.07 cubic meters.
