Answer:
96π
Step-by-step explanation:

V=96π
You know that 3 times 2 is 6 so 30'times 20 equals 60
In this case we use intersecting secant theorem
According to this theorem, GF*GE = GH*GA
So,we plug in the values
(x-3)*(x-3+9) =(x-2)*(x-2+6)
(x-3)*(x+6) =(x-2)*(x+4)
x^2 +6x -3x -18 =x^2 +4x -2x -8
x^2 +3x -18 =x^2 +2x -8
x^2 +3x -18 -x^2 -2x +8 =0
x -10 =0
x=10
So,FG =x-3 = 10-3 =7
Answer:
I think the answer would be 0.2
Step-by-step explanation:
Angle between 16 and 18 = 90 + 55 = 145°
