Answer:

A,B,C,D,E

Step-by-step explanation:

the relationship given between the area and circumference is:

\text{Area} = 16 \times \text{Circumference}

Using the formulas for area and circumference of the circle

\pi r^2 = 16(2\pi r)

solving:

r^2 = 32r

r = 32\,\text{units}

convert this into diameter

2r = d = 2(32)\,\text{units}

d = 64\,\text{units}: Diameter of circle O

Now, the question is asking us to select all such diameters that can fit completely inside this circle O

So, all we need to do is just select all circles that have a diameter less than 64 units. All such circles that have a diameter less than 64 units will completely fit inside the circle O.

Hence, the circles that fit inside circle O are: A,B,C,D,E

Answer:

If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.

Out of these, Bloopin and Rudy are together in 4!=24 times.  Similarly Rudy and Bloopin will be together 4!=24 times.  So the number of ways they are not together is 120-24-24=72 ways.

Hope this helps.    :)

Step-by-step explanation:

Spanish:

Si los renos no luchan, hay 5! = 120 formas de alinearlos en línea recta.

De estos, Bloopin y Rudy están juntos en 4! = 24 veces. De manera similar, Rudy y Bloopin estarán juntos 4! = 24 veces. Entonces, el número de formas en que no están juntas es 120-24-24 = 72 formas.

Espero que esto ayude       :)
