1. Radical 3 + 1 or radical 3-1
2. Set waist as X (the following * denotes a multiplier sign)
X * x divided by 2 = 3 (the area of an isosceles right triangle is 3)
X = root 6
Bottom edge = 2 root sign 3 (sum of two waist squares = hypotenuse Square)
Height = 2 * root 3 divided by 2 root 3 = root 3
So waist = root 6, height = root 3
3. Let the bottom radius be x and the diameter be 2x
14 times the square of X, height = diameter = 2x
Because volume = volume = bottom area
So 3.14 times the square of X * 2x = 6.28
x=1
So the bottom radius is one meter
