Almost all stoichiometric problems can be solved in just four simple steps:
- Balance the equation.
- Convert units of a given substance to moles.
- Using the mole ratio, calculate the moles of substance yielded by the reaction.
- Convert moles of wanted substance to desired units.

Without words you might not understand what is being asked to do.
Well, it has notation in it so when it is turned into function notation you will know how to reverse it and put it back the same way.
Interval notation tells you what values where the function is defined. It’s defined all the way from negative infinity to positive 2, then there’s a gap all the way to positive 8, then we continue on to positive infinity. So x, would be literally every single number besides the number between 2 and 8. Oh and don’t forget that brackets mean included, so 2 is also a value that’s acceptable.
x is less than or equal to 2
and
x is greater than 8
The formula for area of a circle is A=rsquared*3.14. Divide 5.5/2 to get 2.75. Mulitply 2.75 times 2.75 to get approximately 7.56. Then, multiply that times 3.14 to get approximately 23.74.
Answer=23.74 yards
