Answer:
you can always use sin or cos or tan in these situations
S=θr
10.91=θ5
10.91/5=θ
therefore
θpie/180= your answer in radians
The volume of a sphere can be calculated as

Where r is the radius of the sphere
We want to calculate half of the volume, then we must divide that volume by 2

Now we must find the radius of our sphere, the segment AB is the diameter of the sphere, and the radius is half od the diameter, then

Let's put it into our equation

The problem says to use

Then

Final answer:
The formula that can be used to calculate the volume of water inside the fish bowl is
Depends. what are the numbers for both triangles?
Answer:
m∠XAZ = 40°
Step-by-step explanation:
Since ∠YAU, ∠YAZ and ∠XAZ are the angles based at a point on a straight line, and the sum of the all angles on a line is 180°.
Therefore, m∠YAU + m∠YAZ + m∠XAZ = 180°
50° + 90° + m∠XAZ = 180°
m∠XAZ = 180° - 140°
= 40°
Therefore, measure of angle XAZ is 40°.
