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 :

table 3 represents a direct variation function. : )

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
