Answer:
x = 66°
Step-by-step explanation:
In order to solve this, we need the sum of all interior angles which can be found by using the following formula where "n" is the number of sides the polygon has...
Now we use the formula and get...
180(n - 2) = 180(4 - 2) = 180(2) = 360
Now in order to find angle "x," we just substract the values of the other angles from 360, and so we get...
360° - 103° - 133° - 58° = 66°
Now we know that x = 66°

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.
