Name the ordered pair that corresponds to an angle of a pi radians

3π (540°) and 5π(900°)

Step-by-step explanation:

π radian = 180° degree

in the trigonimitrical cercle each point is taken by many values

so π position is also -π position

to move from π to -π you should move 360° (wich is 2π) backwards

π-2π = π

so  -π = π +2π

you can get as much as you can of values similar to π using the formula :

π + 2*k*π where k is a relative number

π+ 2*1*π = 3π

π+2*2*π = 5π

3π is 540°

5π is 900°

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
