Answer:
The number of employees in 8 years is 442
Step-by-step explanation:
Given:
Decreasing rate = 7%
Current number of employees = 790
To Find:
The number of employees after 8 years is this same rate continues =?
Solution:
Let the number of employees after 8 years be x
The current number of employees is:
---------------------------------(1)
since the decrase rate is 7% we use 0.07
So after 8 years , eq (1) can be rewritten as
x= 442.005
x= 442 (approx)
The volume of a sphere is given by the equation 
, where r is the radius.
We are given the diameter of the sphere, but recall that the diameter is twice the radius:
. So the radius is half of the diameter: 
.
Half of 8 cm is 4 cm.
We substitute this for r in the equation and we use 3.14 for <span>π.</span>
