By definition, the surface area of the sphere is given by:
Where,
r: sphere radio
Clearing r we have:

Substituting values:

Then, the volume of the sphere is given by:
Substituting values we have:
Answer:
the volume of the sphere is:

28 rounds up to 30.
32 rounds down to 30.
21 rounds down to 20.
38 rounds up to 40.
42 rounds down to 40.
30 + 30 + 20 + 40 + 40 = 160
Answer: C. 160 min
Answer for question 1:
2 3/6 or 2 1/2 miles
Step-by-step explanation:
1/3 is 5/6 so you: 5/6 x 3=15/6. Then you turn the mixed number to a whole number: 15/6=2 and 3/6. You can also simplify it to 2 and 1/2.
