The correct answer is that the variability is 2.0 times as large.

In the first set, the MAD is 1.2.

In the second set, the MAD is 0.6.

Dividing 1.2 by 0.6 gives us a factor of 2.

Answer:

The approximate area of the circle is 2462 centimeters².

Step-by-step explanation:

Given:

John and Becky measured the circle-shaped part of a sun they drew on the sidewalk. The diameter of the circle is 56 centimeters.

Now, to get the area of the circle approximately.

Diameter of the circle = 56 centimeters.

So, the radius (r) of the circle = $\frac{Diameter}{2} =\frac{56}{2}=28\ centimeters.$

Using 3.14 for π.

Now, to get the area of circle by putting formula:

$Area=\pi r^2\\\\Area=3.14\times 28^2\\\\Area=3.14\times 784\\\\Area=2461.76\ centimeters^2.$

Approximately the area of the circle = 2462 centimeters².

Therefore, the approximate area of the circle is 2462 centimeters².
