First, divide the fractions into a decimal format.
8/3=2.667
-11/3=-3.667
Second, find the placement of the decimal.
Taking the arcsin of both sides of the equation, you get ...
... 90° -x = {-60°, -120°}
So ...
... x = 90° -{-60°, -120°} = {150°, 210°}
The appropriate choice is ...
... 210
H, r
Surface Area = 2πrh
If the h, is now h/3 and the r, now r/3
Surface Area = <span>2π*r/3*h/3
= </span><span>2πrh/9
</span><span>
The modified surface area is reduced by 9 times.

Step-by-step explanation:
speed = distance/time
we know the speed and the time (11:45am to 1:45pm = 2 hours).
distance = speed × time = 56 m/h × 2 h = 112 miles
It would be a right angle because all the angles are less than 90 degrees
