Answer:
x = 20
Step-by-step explanation:
The 3 arcs UV, VW, WX form a semicircle, so sum to 180° , that is
4x + 2 + x + 78 = 180
5x + 80 = 180 ( subtract 80 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
Answer: lateral surface area = 119.4cm^2
r = 2 cm.
h = 9.5 cm.
Steps:
Lateral surface area of a cylinder = 2πrh
r = radius h = height π = pi
2π(2)(9.5)
2π(19)
38π = 119.38052

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:



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 
So

The magnitude of the claimed earthquake would be 13.67.
