Answer: 
Step-by-step explanation:
The formula for calculate the volume of a cylinder is:

r is the radius of the cylinder and h is the height of the cylinder.
Given the diameter of 3 inches, calculate the radius of the cylinder with:
(Where d is the diameter)

Knowing the height and the radius, you can calculate the volume of the entire can of tuna:

As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:

Answer:
83
Step-by-step explanation:
The total angle of a flat line is 180. If you subtract the angle of 2 from 180 you get 83 which is the angle of 1.
What type of math is this??? Geometry? Algebra?
The answer would be C.
Sin2 cot2=sin2*cos2/sin2=cos2
Which is not equal to the others.
