which set of number best describe the number pie(3.14)?

Question

a. integers
b. rational
c. irrational
d. reals

Answer 1

TT is an irrational number.

integers are whole numbers, positive or negative.
rational numbers can be expressed as a fraction.
irrational numbers never end or repeat
real numbers are even roots of positive numbers (vs imaginary numbers, even roots of negative numbers)

Answer 2

1

Answer 3

Although pi is a real number (d) a better, more specific answer also appears on the list. Real numbers can be divided into two disjoint sets: rational numbers that can be expressed exactly as the division of an integer by a nonzero integer, and irrational numbers that cannot. Even though you often see rational approximations of pi such as 22/7 or 3.14, pi cannot be expressed exactly as a ratio of integers. Pi is therefore an irrational number (c).

Answer 4

Pi (no e) is an irrational real number.

Integers are whole numbers, rationals can be expressed as a fraction, irrationals cannot be expressed as a fraction and 'real' describes all non-complex numbers, everything you can think of from negative infinity to positive infinity.

All integers are a rational, but not all rationals are integers, all integers, rationals and irrationals are real, and reals are either rational or irrational.

As has been previously mentioned, pi is transcendental, which is a further class of irrational numbers. Other transcendental numbers are e (used a lot in calculus) and non-specific trig values (things like sin(2) or cos (9))

Answer 5

"Pie" is the name of a round, baked dessert.

"Pi" is a real and irrational number. But I suppose you could say that being an irrational "best" describes Pi because real numbers could still be rational or irrational.

Answer 6

Answer 'd' would be best. Although technically irrational, pi is actually transcendental. Irrational numbers may be the solutions of polynomial equations with integer coefficients, but pi cannot.

Answer 7

Steak & kidney

(you've already got the answer)

but you also need to know that Pie is meat covered with pastry

the symbol for 3,142 is Pi

Answer 8

It's irrational. Actually, it's called transcendental...you can't represent it with square roots. That's a special kind of irrational number.

Answer 9

Irrational, because it doesn't contain complete and whole numbers.
