The volume of a sphere is given by the formula V = (4/3)Ï€r^3, where r is the radius.

Given that the volume of the sphere is 72m^3, we can equate the formula to 72 and solve for the radius.

72 = (4/3)Ï€r^3
72 * 3/4Ï€ = r^3
54Ï€ = r^3
r = (54Ï€)^(1/3)

Since the radius of the sphere is the same as the radius of the cone, we can substitute the radius into the volume formula for a cone.

The volume of a cone is given by the formula V = (1/3)Ï€r^2h, where r is the radius and h is the height.

For the cone, the height is equal to the sphere's diameter, which is 2 times the radius.
h = 2r

Substituting the radius and height into the formula, we get:

V = (1/3)Ï€((54Ï€)^(1/3))^2(2((54Ï€)^(1/3)))
= (1/3)Ï€(54Ï€)^(2/3)(2(54Ï€)^(1/3))
= 108Ï€(54Ï€)^(1/3)

So, the volume of the cone with the given conditions is 108Ï€(54Ï€)^(1/3) cubic meters.

I apologize for the incorrect response.

Let's try again to find the volume of the cone.

Given that the volume of the sphere is 72m^3, we can equate the formula to 72 and solve for the radius.

72 = (4/3)Ï€r^3
r^3 = (3/4Ï€)(72)
r^3 = 27Ï€
r = (27Ï€)^(1/3)

Since the radius of the sphere is the same as the radius of the cone, we can substitute the radius into the volume formula for a cone.

The volume of a cone is given by the formula V = (1/3)Ï€r^2h, where r is the radius and h is the height.

For the cone, the height is equal to the sphere's diameter, which is 2 times the radius.
h = 2r

Substituting the radius into the volume formula for the cone:

V = (1/3)Ï€((27Ï€)^(1/3))^2(2((27Ï€)^(1/3)))
= (1/3)Ï€(27Ï€)^(2/3)(2(27Ï€)^(1/3))
= (1/3)Ï€(27Ï€)(2)(27)^(1/3)
= 18Ï€(27)^(1/3)

So, the volume of the cone with the given conditions is 18Ï€(27)^(1/3) cubic meters.

To find the volume of a cone, you need the radius of the cone's base and its height. In this case, the radius of the cone is the same as the sphere's radius, and the height of the cone is equal to the sphere's diameter.

Let's start by finding the radius of the sphere using its volume. The volume of a sphere can be calculated using the formula:

V = (4/3) * π * r³

From the given information, we know that the volume of the sphere is 72 m³. Plugging this value into the formula, we have:

72 = (4/3) * π * r³

To solve for the radius, we can rearrange the equation:

r³ = (3/4) * (72 / π)
r³ = 27

Taking the cubic root of both sides, we get:

r = 3

Now, since the height of the cone is equal to the sphere's diameter, it is equal to twice the radius. Therefore, the height of the cone is:

h = 2 * 3 = 6

Now that we have the radius (r = 3) and height (h = 6) of the cone, we can calculate its volume using the formula:

V = (1/3) * π * r² * h

Substituting the values into the formula, we have:

V = (1/3) * π * 3² * 6

V = (1/3) * π * 9 * 6

V = 54Ï€

Therefore, the volume of the cone is 54Ï€ cubic units.
