Solution -
The sphere is centered in the cube, so diameter of the sphere is equal to the side of the cube. Hence ,the radius of the sphere is half of the length of the side.
If the length of side of the cibe = a , then radius of the sphere is
Volume of the cube = a³, volume of the sphere = π(radius)³ =
π(
)³
volume of the cube outside the sphere = volume of the cube - volume of the sphere
= π(
)³
=
=a³(1 - )
Answer:
Z(-0.2, 2.2).
Step-by-step explanation:
We will use section formula when a point, say P, divides any segment ,say AB, internally in the ratio m:n.
We have been given the points of segment XY as X at (-2,1) and Y at (4,5) and ratio is 3:7.
Upon substituting coordinates of our given points in section formula we will get,
Therefore, coordinates of point Z will be (-0.2, 2.2).
