Answer:

Step-by-step explanation:

For all shapes, the surface area will go up by a factor of 9 (3^2). This is true of spheres, cones, cubes, pyramids, torusses, everything.

The surface area of any body is proportional to the square of any linear dimension. Triple a linear dimension and you get a 9 fold increase in surface area. This is as true for pretzels as it is for spheres and cubes.

Which number is rational?

Vitek1552 [10]

<span>The answer is D.

Don't be fooled sqrt(10) goes on for many many places and if you know the 20th digit is a 9 you have a 1 in 10 chance of predicting what the next digit is. The same is true for pi and sqrt(2). The sqrt root of 16 is 4 which is rational. It could be - 4 which is still rational. The other 3 go on forever and each one has the property of unpredictability of the next digit if you know the current digit.</span>
