Answer:
By summing cylindrical slabs of infinitesimal height and different radii place one on the other such that margin of between real and intended volume is minimum.
Step-by-step explanation:
A spherical slab is characterized by the radius as its inherent variable and cylindrical slabs by its radius and height. The volume of the spherical slab can be approximated by summing cylindrical slabs of infinitesimal height and different radii place one on the other such that margin of between real and intended volume is minimum. (Please see image attached below for further details).

The equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.
<h3>What is the equation of a line passing through two given points in a 2-dimensional plane?</h3>
Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by

The graph of the picture shows two clear points (4.5. 0) and (0, 9)

Hence, the equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.

Answer:
   multiply the left side of the constant vector by the inverse matrix
Step-by-step explanation:
The matrix equation ...
   AX = B
is solved by left-multiplying by the inverse of A:
   A⁻¹AX = A⁻¹B
   IX = A⁻¹B . . . . . the result of multiplying A⁻¹A is the identity matrix
   X = A⁻¹B . . . . . B needs to be multiplied by the inverse matrix
