Answer:
this is the formula for a volume of a sphere
4
/3*π*r^3 so plug in the radius 
4/3*3.14*3^3=
4/3=1.33333333
1.333*3.14=4.186666562
4.186666562*3^3=113
the volume of the sphere is 113

Answer:
1. 98.7 km
2. 303.5 degree 
Step-by-step explanation:
Using the alternate angle, the angle at B will be 50 + 10 = 60 degree. 
To calculate the length AC of the returning journey, use cosine formula to calculate it.
To find the bearing of the returning journey, use sine rule to calculate it.
