Answer:
About 11494.04
Step-by-step explanation:
There is no sphere shown above but I can still get you the answer:
The formula for the volume of a sphere is π*r³
Putting in the radius, we get:
*π*14³=
*π*2744=
*π=
3658.66*π≈11494.04
Points A, B, C, and D are located on a line. A is at (-6,13), D is at (2,14), C is the midpoint of AD and B is the midpoint of A
C. What is the sum of the coordinates of point B? Express the answer as a common fraction.
1 answer:
Answer:
37/4
Step-by-step explanation:
The sum of the coordinates of point B is the weighted average of the sum of coordinates of points A and D. Those sums are A=-6+13 = 7; D=2+14=16.
Point B is 3/4 of the way from point D to point A, so the sum of its coordinates will be ...
(3×7 +1×16)/4 = 37/4
_____
The coordinates of point B are (-4, 13.25), so their sum is 9.25 = 37/4.
