Answer:
Step-by-step explanation:
side of square=10+10+20=40 m
area of square=40×40=1600 m²
area of small square=π10²=100 π m²
area of bigger semi circle=1/2 ×π×20²=200 π m²
reqd. area of shaded region=1600-(100π+200π)=1600-300π m²
≈1600-300×3.14
≈1600-942
≈658 m²
Answer:
1/2

Answer:
A
Step-by-step explanation:
the angle is 115.6
Hope this helps
when a number is raised to the power of a rational number it becomes a root of the denominator's order and the number inside the root is raised by the power of the numerator
for example
![x^{\frac{a}{b} }=\sqrt[b]{x^a}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Ba%7D%7Bb%7D%20%7D%3D%5Csqrt%5Bb%5D%7Bx%5Ea%7D)
in this case
![32^{\frac{3}{5} }=\sqrt[5]{32^3}](https://tex.z-dn.net/?f=32%5E%7B%5Cfrac%7B3%7D%7B5%7D%20%7D%3D%5Csqrt%5B5%5D%7B32%5E3%7D)
![=\sqrt[5]{32768}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B5%5D%7B32768%7D)
=8
These are the steps I took to solve this problem:
1.) 319 million is 319,000,000 (6 zeros).
2.) 319,000,000 divided by 823,000 is 387.606318348. (I did this step to find how many "times larger")
3.) The U.S. is about 388 times larger than Columbus, Ohio.
I may have not gotten this right, but all the same, I hope this helps and have a good night! :D
