What is the volume of the first octant of a sphere?
Answer and Explanation:
The total volume of a sphere of radius r is given as V = 4 3 π r 3 .
The volume of a sphere lying the first octant is equal to one-eighth of the total volume.What is the first octant value?
The first octant is the area beneath the xyz axis where the values of all three variables are positive.
The first octant is one of the eight divisions established by the coordinate signs in a three-dimensional Euclidean coordinate system.
For example, the first octant has the points (2,3,5).The positive octant is the region of 3D space corresponding to x ≥ 0 , y ≥ 0 , z ≥ 0 .
Let denote the portion of the solid sphere x 2 + y 2 + z 2 ≤ 1 in the positive octant.
What is the concept of octant?
An octant in solid geometry is one of the eight divisions of a Euclidean three-dimensional coordinate system defined by the signs of the coordinates.
It is similar to the two-dimensional quadrant and the one-dimensional ray.
Three axial planes (x=0, y=0, z=0) divide space into eight octants.
