A right circular cone is exactly fitted inside a cube in such a way th...
To find the volume of the cone, we first need to determine the height and radius of the cone.
Let's assume the side length of the cube is "a". Since the volume of the cube is given as 512 cubic cm, we can calculate the side length using the formula:
a³ = 512
Taking the cube root of both sides, we find:
a = 8 cm
Now, let's consider the cone. The base of the cone is a circle that touches the edges of one face of the cube. Since the edges of the cube are all equal to "a", the diameter of the base of the cone is also equal to "a". Therefore, the radius of the base of the cone is equal to half the side length of the cube:
radius = a/2 = 8/2 = 4 cm
The height of the cone is the distance from the vertex (which is on the opposite face of the cube) to the center of the base. Since the vertex is on the opposite face, the height is equal to the side length of the cube:
height = a = 8 cm
Now we can calculate the volume of the cone using the formula:
Volume = (1/3) * π * radius² * height
Plugging in the values we found:
Volume = (1/3) * π * 4² * 8
= (1/3) * π * 16 * 8
= (1/3) * π * 128
≈ 134 cubic cm
Therefore, the approximate volume of the cone is 134 cubic cm, which corresponds to option (c).
