Sidana [21]
The surface area of a sphere is S=4 \pi  r^{2} where r is the radius;
The circumference is 2 \pi r=27 in so that r= \frac{27}{2 \pi }=4.5 in using this value we can evaluate the surface area of 1 ball as:
S=4 \pi r^{2} =4 \pi  (4.5)^{2} =254.3  in^{2}
For 100 ball you get: 100*254.3=25430  in^{2}

Why don’t Noble Gases have a value for electronegativity?
kumpel [21]

Answer:

The answer is 1.

Step-by-step explanation:

Nobel gases have full shell of valence electrons, that is why they tend to not enter any chemical reactions because they are satisfied while metals have very few electrons in the valence shell, so they are active in any chemical reaction.

Marta_Voda [28]

Answer:

c. 0.3421

Step-by-step explanation:

The computation of the probability of selecting the biased coin is shown below:

The probability of any coin selected is 1 ÷ 2

The probability in the case when the biased coin chosen & wins 1 ÷ 2 (1 - 0.74)

And, the win probability is 1 ÷ 2  (1 - 0.74) + 1 ÷ 2  (1 - 0.5)

Now the probability of biased or win is

=  {1 ÷ 2 (1 - 0.74)} ÷ { 1 ÷ 2  (1 - 0.74) + 1 ÷ 2  (1 - 0.5)}

= 0.13 ÷ 0.38

= 0.3421

Hence, the correct option is c. 0.3421
