x = 4°
Step-by-step explanation:
all angles in a triangle sum up to 180°
6x + 38° + 5x + 8° + 90° = 180 °
11x +136° = 180°
11x = 44°
x = 4°

Answer:
3052.1 in³
Step-by-step explanation:
The volume of a sphere is given by the formula ...
V = 4/3πr³ . . . . r is the radius
The radius is half the diameter, so is 9 in. Then the volume is ...
V = (4/3)(3.14)(9 in)³ = 972(3.14) in³ ≈ 3052.1 in³
