1. A surface consists of a quarter of a circle of radius R=3 m (fig). It is located with its edge a=2.0m
below the water surface. Calculate the magnitude and direction of the resultant force on the upper
surface.
How can the buoyancy force on a body be calculated

a is the right answer

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides

step-by-step explanation:

answer is

b.
