Answer:
Part 1) The volume of the ball is 256 cm³
Part 2) The radius of the ball is 3.94 cm
Step-by-step explanation:
Part 1) we know that
The density is equal to divide the mass by the volume
D=m/V
Solve for the volume
The volume is equal to divide the mass by the density
V=m/D
In this problem we have
m=128 g
D=0.5 g/cm³
substitute
V=128/0.5=256 cm³
Part 2) what is the radius of the ball?
we know that
The volume of the sphere (ball) is equal to
we have
assume
substitute and solve for r
243.87 and 132.37 thts the answer
The percentage change in the staff strength of the grocery store is 10.53%.
<h3>How to find the percentage change?</h3>
We are given;
Number of employees in store = 38 employees
Number of additional people hired = 4 employees
Thus, percentage change in their staff is;
4/38 * 100% = 10.53%
Thus, the percentage change in the staff strength of the grocery store is 10.53%.

Answer:
A
Step-by-step explanation:
x=6.28111...
100 x=628.111...
1000x=6281.111...
subtract
900x=5653
x=5653/900
density of iodine=785×5653/900≈4930.672222...
