Let c be a circle with radius 2–√. which of the following statements is true? the area of c is a rational number because it is the product of 2, a rational number, and π, an irrational number. the area of c is an irrational number because it is the product of 2, a rational number, and π, an irrational number. the circumference of c is a rational number because it is the product of 22–√, an irrational number, and π, an irrational number. the circumference of c is an irrational number because it is the product of 22–√, a rational number, and π, an irrational number.

We are given radius = sqrt(2).

And sqrt(2) is an irrational number because we can not write it as a simplest fraction p/q.

Also π is an irrational number because we cannot write down a simple fraction that equals π.

We know area of a circle = π r^2 and

Circumference of a circle = 2π r.

If we square square root 2, we would get 2.

That is rational number.

But if we multiply an irrational number by a rational number, it would give an irrational number only.

Therefore,  true statements are :

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
