Answer:
True, all integers are rational numbers.
Step-by-step explanation:
Because each integer can be written as n/1 and integers can be positive and negative. For example, 3= 3/1 , 3 is the rational number. But all rational numbers like 1/2 =0.5 are not an integer. (fractions, decimals are not integers.)
To find the circumference, we will have to multiply the length of the diameter by pi
Mathematically, we have this as;
Answer:
√72 - √27 + 2·√8
√(9·4·2) - √(9·3) + 2·√(4·2)
3·2·√2 - 3·√3 + 2·2·√2
6·√2 - 3·√3 + 4·√2
10·√2 - 3·√3
The last answer is correct.
