Segment AB has a midpoint M. If A is located at (4, 2) and M is located at (7, -3), what are the coordinated of B?

(
−
8
,
3
)

Explanation:
The coordinates are ordered pairs with the
x
value listed first.
The change in the
x
position is
4
−
−
2
=
6

The change in the
y
position is
7
−
5
=
2

Since the midpoint is halfway between A and B, the change will stay the same, so
x
is
−
2
−
6
=
−
8
and
y
is
5
−
2
=
3

SA=1017.88

V=3053.63

Step-by-step explanation:

SA=4pi times r to the 2

V=4 /3pi times r to the 3
