You haven't shared all of the question, so I'll guess that you want to find "how fast is the area of the sphere increasing?"
Area of a sphere = 4*pi*r^2
Rate of change of area of a sphere with respect to radius r:
dA/dr = 8*pi*r*(dr/dt)
Here, that would come out to
dA/dr = 8*pi*r*(2 inches / sec)
If you meant, "how fast is the volume of the sphere increasing?" you'd need to use a different equation:
V = (4/3)*pi)*r^3
and go through a similar process.
Answer:
0
Step-by-step explanation:
additive inverse means any number to make the sum zero. in this case 4 +(-4)=0
The common ratio is the fifth term divided by the fourth term: -40/-8 = 5.
The seventh term is :
$116.02 interest will be earned in 9 months
Step-by-step explanation:
The formula for simple interest is given by:

Here
P is the initial amount
r is the interest
t is the time measured in years
Given
P = $2475
r = 6.25% = 
t = 9 months
Converting time into year by dividing by 12

Putting the values in the formula

Rounding off to nearest hundredth
I = $116.02
Hence,
$116.02 interest will be earned in 9 months
