For any point to be in the first quadrant, it must have a positive "x" value and "y" value. 
If x = 1 then y = 2, a point with both x and y positive values which would be in the First Quadrant.

1.a sphere with a radius of three units

 
By definition, the volume of a sphere is:
 V = ( \frac{4}{3} ) (\pi) (r ^ 3)

 Substituting values we have:
 V=(\frac{4}{3})(\pi)(3^3)
 Rewriting we have:
 V = (4) (\pi) (3 ^ 2)

V = (4) (\pi) (9)

V = 36\pi

 2.a cone with a diameter of twelve units and a height of three units
 
 By definition, the volume of a cone is given by:
 V =  \frac{1}{3}  (\pi) (r ^ 2) (h)

 Substituting values we have:
 V =  \frac{1}{3} (\pi) ((\frac{12}{2}) ^ 2) (3)

 Rewriting we have:
 V = (\pi) (6 ^ 2)

V = 36\pi

If two matrices, A and B, are equal, which of the
alexandr402 [8]

If A and B are equal:

Matrix A must be a diagonal matrix: FALSE.

We only know that A and B are equal, so they can both be non-diagonal matrices. Here's a counterexample:

A=B=\left[\begin{array}{cc}1&2\\4&5\\7&8\end{array}\right]

Both matrices must be square: FALSE.

We only know that A and B are equal, so they can both be non-square matrices. The previous counterexample still works

Both matrices must be the same size: TRUE

If A and B are equal, they are literally the same matrix. So, in particular, they also share the size.

For any value of i, j; aij = bij: TRUE

Assuming that there was a small typo in the question, this is also true: two matrices are equal if the correspondent entries are the same.
