Please check puzzle dated 14.06.2021

If the capacity of a cylindrical tank is 4004 m^3 and the diameter of its base is 14 m, then find the depth of the tank?

Solution given is
Let the depth of the tank be h meter
πr²h = 4004
h = 4004/ πr²
h = (4004 x 7/22 x 1/14)
h = 91 m.

I think admin has considered 2r =14 only in place of r^2 ( 7^2).

It should be

Let the depth of the tank be h meter
πr²h = 4004
h = 4004/ πr²
h = (4004 x 7/22 x 1/49)
h = 26 m.

Please check and do justice to maths.

Answer is 3
If you pick 2 socks then chances are that both are of two different colors.
When you pick 3 for sure two would be of the same color (as the socks are only of two colors Red and White)
