If you mean average rate of area increase, it is 4pi cm2/cm. Simply take the total change in area, 9pi-1pi=8pi, and divide it by the total expansion.

How do you calculate the average transient rate?
Average Transient Rate
What is the radius of an expanding circle at the moment when the rate of change of its area is numerically twice as large as the rate of change of its radius?
i dont know im only 5 A better answer: I assume you are taking differential calculus? A = (pi) R^2 dA/dt = 2 dR/dt cross multiply and find dA/dR = 2 dA/dR = 2 pi R = 2 R = 1/pi
Find a formula for Poiseuilles Law given that the rate of flow is proportional to the fourth power of the radius and Use k as the proportionality constant?
Rate of flow varies as R^4 where R is the radius or Rate of flow = (k) x (R^4)
What is the relationship between flow rate pressure?
With the increase in flow rate the velocity of the fluid increases. and with the increase in velocity the pressure decreases, because there will be pressure drop (Refer Bernoulli's Theorm). So with increase in Flow rate the pressure decreases.
What the relationships between the surface area of an object and the volume as the object increases in size?
They both increase. The rate of increase of the surface area is equivalent to the rate of increase of the volume raised to the power 2/3.
The area of a circle is increasing at a uniform rate of 8cm square per second Calculate the rate of increase of the radius when the circumference of the circle is 96cm?
A = (pi)(r)2 (dA/dt) = (2(pi)(r)) * (dr/dt) (8) = (2(pi)(96)) * (dr/dt) (dr/dt) = (1) / (24(pi))
What changes would cause the fusion rate in the Suns core to increase?
Increase in the core temperature and decrease in the core radius.
How could adjust the afferent or efferent radius to compensate for the effect of reduced blood pressure on glomerular filtration rate?
increase afferent radius or decrease efferent radius depending on the degree of change in blood pressure
What is the relationship between flow rate and radius size?
Flow rate= radius to the fourth power
Over the history of the human population the average increase rate of populations?
C. exponential
What is the difference between natural increase of a country and fertility rate of a country?
natural increase is a rise population because the birth rate is higher than the death rate and fertility rate is the average number babies born throughout woman's lifetime
What happens to the rate constant of a chemical reaction when the temperature increases?
Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.
What are linear taxes?
Linear taxes is the situation when the average tax rate is 20%. When this happens the tax rate will not increase with a higher income.
Over the history of the human population the average increase rate of populations has been?
Increasing exponentially.
What viscosity level was the fluid flow rate the highest?
The relationship between radius and fluid flow rate is inversely proportional. As radius goes down, fluid flow rate goes up. The highest fluid flow rate will be at the lowest radius.
What is the national average right now for mortgage interest rates?
The national average for a 30 year fixed mortgage rate is 4.89%. This rate can either increase or decrease depending on the loan ammount. As of March 6, 2010, the national average mortgage interest rate for a 30 year fixed rate loan is 5.31%. The national average mortgage interest rate for a 15 year fixed rate loan is 4.68%.
What happened to the rate as the right vessel radius was increased?
Physio Ex Answer: When the right vessel radius was increased the flow rate increases.
