sphere = cylinder + cone

Given that the volume of the cylinder is 36 cm^3:
Volume of the cylinder = πr^2h
36 = πr^2h
36 = πr^2(2r) [height of the cylinder is equal to the sphere's diameter, which is 2 times the radius]
36 = 2πr^3
r^3 = 18/π
r = (18/π)^(1/3)

Now, we need to find the volume of the sphere with the same radius (r):
Volume of a sphere = (4/3)πr^3
Volume = (4/3)π[(18/π)^(1/3)]^3
Volume = (4/3)π((18/π)^(1/3))^3
Volume = (4/3)π(18/π)
Volume = (4/3)(18)
Volume = 24 cm^3

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

Given that the volume of the cone is 253π cm^3:

Volume of the cone = (1/3)πr^2h
253π = (1/3)πr^2h
253π = (1/3)πr^2(2r) [height of the cone is equal to the sphere's diameter, which is 2 times the radius]
253π = (2/3)πr^3
r^3 = 759/π
r = (759/π)^(1/3)

Now, we need to find the volume of the sphere with the same radius (r):
Volume of a sphere = (4/3)πr^3
Volume = (4/3)π[(759/π)^(1/3)]^3
Volume = (4/3)π((759/π)^(1/3))^3
Volume = (4/3)π(759/π)
Volume = (4/3)(759)
Volume = 1012π cm^3

Therefore, the volume of the sphere is 1012π cm^3.

A sculptor created a design by carving a cone out of a cylinder. The cone and cylinder share the same radius and height. If the volume of the cylinder before removing the cone is 54 in.3 , what is the volume of the amount remaining?(1 point) Responses 36 in.3 36 in. cubed 27 in.3 27 in. cubed 40 in.3 40 in. cubed 18 in.3

Given that the volume of the cylinder before removing the cone is 54 in^3:

Volume of the cylinder = πr^2h
54 = πr^2h
54 = πr^2(2r) [height of the cylinder is equal to the radius since it is a cone carved out of a cylinder]
54 = 2πr^3
r^3 = 27/π
r = (27/π)^(1/3)

Now, the volume of the remaining part after carving out the cone is:
Volume of the remaining = 54 - (1/3)πr^2h
Volume of the remaining = 54 - (1/3)π(27/π)^(2)*27/π
Volume of the remaining = 54 - (1/3)π*729/π^3
Volume of the remaining = 54 - 243/π^2
Volume of the remaining = 54 - 243/π^2
Volume of the remaining = 54 - 243/(3.14159)^2
Volume of the remaining ≈ 36 in^3

Therefore, the volume of the amount remaining after carving out the cone is approximately 36 in^3.

She knows the height of the cone is equal to the diameter of the hemisphere, and the volume of the cone is 12 m3 . What is the volume of the whole object?(1 point) Responses 24 m3 24 m cubed 36 m3 36 m cubed 18 m3 18 m cubed There is not enough information to say.

We know the volume of the cone is 12 m^3, and the height of the cone is equal to the diameter of the hemisphere.

Volume of a cone = (1/3)πr^2h
Given that the volume of the cone is 12 m^3, we have:
12 = (1/3)πr^2h
12 = (1/3)πr^2(2r) [height of the cone is equal to the diameter]
12 = (2/3)πr^3
r^3 = 18/π
r = (18/π)^(1/3)

Now, we know that the height of the cone is equal to the diameter of the hemisphere. Hence, the radius of the hemisphere is also (18/π)^(1/3).

The volume of the hemisphere is (2/3)πr^3.
Volume of the hemisphere = (2/3)π[(18/π)^(1/3)]^3
Volume of the hemisphere = (2/3)π(18/π)
Volume of the hemisphere = 12 m^3.

Therefore, the total volume of the object (hemisphere + cone) = Volume of the hemisphere + Volume of the cone = 12 m^3 + 12 m^3 = 24 m^3.

The volume of the whole object is 24 m^3.
