Answer:</h2><h2>Yes, the simplified form of 2 square root of 3 − 2 square root of 3 is rational.</h2>
Step-by-step explanation:
The given expression is 
After performing the subtraction operation, the result is 0 as the terms are equal and opposite in sign, they cancel each other.
Rational numbers are those which can be expressed in the form of fractions, decimals, e.t.c
Since 0 can be expressed as a fraction, it is a rational number.
For eg: 
= 0,
Hence the result of the given expression is a rational number.
The volume of each birthday hat is 56.55 in³ and the 12 hats has a total volume of 678.58 in³
<h3>What is
volume?</h3>
Volume is the amount of space occupied by a three dimensional shape or object.
The volume of a cone is given by:
volume = (1/3) * π * radius² * height
The cone that has a height of 6 inches and a radius of 3 inches. Hence:
Volume = (1/3) * π * 3² * 6 = 56.55 in³
For 12 hats:
Volume = 12 * 56.55 in³ = 678.58 in³
The volume of each birthday hat is 56.55 in³ and the 12 hats has a total volume of 678.58 in³
