Answer:
The coordinates of your position are ,
and
or in coordinates notation the point given by
Step-by-step explanation:
Since you are starting from the origin of a coordinate system, the coordinates of you position are simply going to be how many units you have moved in each direction.
- 7 units in the positive x-axis direction gives you
- Then, being in the x-axis, you move 2 units downward parallel to the z-axis. Here the downward gives you a negative sign for the z coordinate, hence,
.
- Now,
is given due to the fact that there is no movement in the y-axis direction or you can also say that all the movement have been perpendicular to the y-axis and therefore, your position in this axis is zero.

My answer:
As given in the question, we know that:
The ratio of the area of the circle to the area of the square is π/4
- The formula to find the volume of the cone is:
V = 1/3*the height*the base area
<=> V1 = 1/3*h*π
- The formula to find the volume of the pyramid is:
V2 = 1/3*the height*the base area
<=> V = 1/3*h*4
=> the ratio of volume of the cone to the pyramid is:
=
= (1/3*h*π ) / ( 1/3*h*4
)
= π/4
S we can conclude that the volume of the cone equals π/4 the volume of the pyramid
Hope it will find you well.
