The answer is 1
Hope this helped :)
Answer:
178.571429
Step-by-step explanation:
Area of square - 10*10 m = 100m
Area of the semicircle = Diameter = 10m, so the radius = 5m
Area of circle = ![\pi r^{2}](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D)
=> Area = 22/7 * 25
=> 78.5714286
Area of figure = 78.5714286 + 100 = 178.571429
Hope it helps :)
actually this equation is correct but I didnt understand what it wants
Answer:
The magnitude of the claimed earthquake would be 13.67.
Step-by-step explanation:
The 1906 earthquake had a intensity of A and a magnitude of 7.8.
S is going to have the same value, so i am going to write as 1. So:
![\log{A} = 7.8](https://tex.z-dn.net/?f=%5Clog%7BA%7D%20%3D%207.8)
![A = 10^{7.8}](https://tex.z-dn.net/?f=A%20%3D%2010%5E%7B7.8%7D)
![A = 63095734.448](https://tex.z-dn.net/?f=A%20%3D%2063095734.448)
Many pundits claim that the worst is yet to come, with an earthquake 748,180 times as intense as the 1906 earthquake ready to hit San Francisco.
So ![A = 748180*63095734.448](https://tex.z-dn.net/?f=A%20%3D%20748180%2A63095734.448)
So
![R = \log{A} = \log{748180*63095734.448} = 13.67](https://tex.z-dn.net/?f=R%20%3D%20%5Clog%7BA%7D%20%3D%20%5Clog%7B748180%2A63095734.448%7D%20%3D%2013.67)
The magnitude of the claimed earthquake would be 13.67.
