The base of this cylinder is a circle with a radius of 3 units (the high of the rectangle).

And the high of this cylinder is 2 units.

Volume of cylinder is given by the formula :

V= h.pi.r²

so V= 2×3.14×9

Prove that n is odd if and only if 3n + 6 is odd by contradiction.
Reil [10]

Step-by-step explanation:

o - odd number

e - even number

n + e =o, if n is odd...rule 1

n + e = e, if n is even...rule 2

n × o = o, if n is odd...rule 3

n × o = e, if n is even...rule 4

thus if 3n +6 = o,

then 3n must be odd, following rule 1

=> 3n = o, then n is an odd number, following rule 3
