Area of sector=sectorfraction times area
sector fraction=angle/360
area=pir^2
r=10
area=pi10^2=100pi
so
5pi/100pi=xdeg/360
1/20=x/360
times both sides by 360
18=x
answer is 18 degres
An earthquake with a rating of 3.8 can cause destruction in areas of up to 100 kilometers that are populated.
<span>R = log x </span>
<span>R = rating of the earthquake's size on the Richter scale </span>
<span>x = ratio of earthquake intensity to a minimum level of intensity</span>
