The volume of the sphere is 
Explanation:
Given that the diameter of the toy ball is 12.5 inches
We need to determine the volume of the toy ball.
The radius of the toy ball is given by
Thus, the radius of the toy ball is 6.25 in
The volume of the sphere can be determined using the formula,
Substituting the values, we get,
Multiplying, we get,
Substituting 
, we have,
Simplifying, we get,
Thus, the volume of the sphere is

Answer:
Q1:
150 pages is the answer
2 hours= 60+60minutes
So 120/40 =3
Answer= 50×3= 150.
Q2:
Using Work=men×days we get
Work=20×20
Work=400
Now, work is same and number of days are to be calculated
400=25×days
days= 16
400 = 25 x 16
so it will take 16 days

Answer:
- 2 ≤ n < 8
Step-by-step explanation:
The closed circle at - 2 indicates that n can equal - 2
The open circle at 8 indicates that n cannot equal 8
Otherwise n can be all value between - 2 and 8 including - 2, thus
- 2 ≤ n < 8
