Answer:

12.6

Step-by-step explanation:

To find the area of a circle, you need to use the formula A=\pi r^{2}

We have r, so we need to plug it into the formula.

A=\pi (2)^{2}

A=\pi (4)

A=12.5663706...

Since we need to round to the nearest tenth, your final answer should be 12.6

Answer:

The first one would be m^30n^20p^30  

And the second one would be a^2 / d^4  

Step-by-step explanation:

For 1, you have to multiply the inner exponents by the outer one so you get (m^12n^8) times (m^18n^12p^30). Then you mutiply the two together, so you add the exponents, where you get m^30n^20p^30.

For 2, since you're dividing, you have to subtract the exponents so you get a^2d^-4, but since you shouldn't have the negative you turn it into a^2 / d^4

Hope this helps :)
