Answer:
The answer is C
Step-by-step explanation:
First of all let's eliminate the answers that do not make sense. For A. numbers are NOT irrational because they are a fraction. Numbers are also not irrational because they are a repeating number. C and D are both correct as fractions and terminating decimals are both rational numbers.
34/3≈11.33333333
By using a certain formula you can convert repeating decimals to a fraction. But most people know that .3333333 is 1/3. This gives us 11 1/3 as our answer. So what does it match? It is not a terminating decimal. It repeats but can be written as a fraction. Therefore our answer is C) Rational, because it is a fraction.
You answer would be -2 and 1/10
Perimeter of bigger disc = 2π*24 inch
perimeter of bigger disc = 2π*8 inch
number of rotations =2π*24/2π*8 = 3
