Answer:
The area of a circle is defined as A=pi*R*R. To find the radius, first divide A/pi. The answer would be the square of the radius; therefore, the square root of A/pi is the radius of the cylinder. Volume is defined as V=pi*R*R*H, or V=A*H. Dividing the volume by the area V/A would result in the height of the cylinder.

Answer:
a) y = 4e^(0.06t)
b) 0.06
c) 11.55 hours
d) 6.9 million
Step-by-step explanation:
When the growth rate (millions per hour) is proportional to the number (millions), the relationship is exponential. The growth rate is the constant of proportionality.
a) Formula for y(t):
y = 4e^(0.06t)
__
b) The growth constant is 0.06, the multiplier of t in the exponential function. It is the constant of proportionality in the given differential equation:
y' = 0.06y.
__
c) The doubling time is found from ...
2 = e^(0.06t) . . . the multiplying factor is 2 to double the original number
ln(2) = 0.06t . . . . taking natural logs
ln(2)/0.06 = t ≈ 11.55 h . . . . doubling time
__
d) Put t=9 into the formula from part (a). After 9 hours, there will be ...
y(9) = 4e^(0.06·9) ≈ 6.9 . . . . million bacteria present
