The dotted lines indicate that this object is a sphere, so we will use the formula for finding the volume of a sphere to solve this problem.
Volume of a sphere: 4/3r³
The figure shows us that the radius of the sphere is 2.8 cm, so we will plug in 2.8 for r in the formula.
4/32.8³ = 91.95
The volume of the figure is 91.95 cm³.

Answer:
Speed of car B is 33 km/h and speed of car A is
Step-by-step explanation:
Let speed of car B be km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A = km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours = km = km
Distance travelled by car B in 4 hours = km
Also, cars A and B are 312km apart after 4 hours.
Speed of car B is 33 km/h and speed of car A is
