How many cones of radius 1 m and height 1 m have total volume equal to the volume of a sphere with a radius 1m?

1 answer:

7 0

Vcone=1/3(hpir^2)
Vsphere=(4/3)pir^3

evaluate
vcone=1/3(1pi1^2)=pi/3
vsphere=4/3pi1^3=4pi/3

pi/3 times what=4pi/3
times both sides by 3
pi times what=4pi
divide both sides by pi
1 times what=4
what=4

4 cones

Shtirlitz [24]

X+y=30
2x-3y=5

y=30-x

2x-3(30-x)=30
2x-90+3x=30
5x=120
x=24

y=30-x
y=30-24
y=6

The positive difference between the two numbers is 18.
