Answer:
![a = \pi {r}^{2}](https://tex.z-dn.net/?f=a%20%3D%20%5Cpi%20%20%7Br%7D%5E%7B2%7D%20)
The radius is half of the diameter. Therefore the radius is 23÷2 = 11.5.
![a = 3.14 \times {11.5}^{2}](https://tex.z-dn.net/?f=a%20%20%3D%203.14%20%5Ctimes%20%7B11.5%7D%5E%7B2%7D%20)
![a = 3.14 \times 132.25 \\ = 415.265](https://tex.z-dn.net/?f=a%20%3D%203.14%20%20%5Ctimes%20132.25%20%5C%5C%20%20%3D%20415.265)
To the nearest tenth = 415.3

Step-by-step explanation:
6.81 times 10^16 is the answer in scientific notation
The additive inverse of something is just what the certain number needs to equal 0. In this case 3+5=8 inches total. In order to get 8 inches to 0 you need to add -8 to 8. So the additive inverse is -8 inches (Always remember your units, in this case inches) Hope this helped :)
