Please give me the correct answer

3 * 10^4 (Choice #2)

Step-by-step explanation:

This is a good time to know your exponent rules. You can do this by calculator which will spit out a massive number, or you if you know your exponent rules, it will be much easier to see.

There may be a better way of answering this question, but it's not popping up in my mind right now, but anyway...

You can divide 9 * 10^2 by the answer choices to see until you get 3 * 10^-2

Since we are dividing exponents as well, note that the exponent rules say that dividing exponents is the same as subtracting the exponent .

Me taking an educated guess at which one to start off which...lets do the second one. 9 / 3 = 3 and since im a geek, I know that 2 - 4 = -2 (for exponent).

You can split this up.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
