Answer: 80.384 cubic cm /min
Explanation:
Let V denote the volume and r denotes the radius of the spherical snowball .
Given :
We know that the volume of a sphere is given by :-
Differentiating on the both sides w.r.t. t (time) ,w e get
When r= 8 cm
Hence, the volume of the snowball decreasing at the rate of 80.384 cubic cm /min.

Firstly, to find speed you need to remember the speed formula:
Speed = Distance ÷ Time
You can do it by doing 2800 ÷ 2 but that gives m/h (metres per hour)
So to convert hours into seconds, you multiply 2 by 7200 (amount of second in 2 hours:
2 * 7200 = 14400 seconds
Now we can do distance ÷ time by plugging the values in:
2800 ÷ 14400 = ≈0.194
