Please have a look at the attached photo.
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.
Answer:
8 hours
Step-by-step explanation:
−0.75x + 18 = -x+20
0.25x = 2
x = 8
Answer:
0.17155425219941%
Step-by-step explanation:
100%/x%=682/1.17
(100/x)*x=(682/1.17)*x - we multiply both sides of the equation by x
100=582.90598290598*x - we divide both sides of the equation by (582.90598290598) to get x
100/582.90598290598=x
0.17155425219941=x
x=0.17155425219941
Hope this helps .. sorry if it’s wrong .
