Find the area and circumference of the circle. Use 3.14 for A.
Kaylis [27]

Answer:

A = 63.59

C = 28.26

Step-by-step explanation:

r = 4.5

Area of a circle:

A = πr²

A = 3.14(4.5²)

A = 3.14(20.25)

A = 63.59

Circumference:

C = 2πr

C = 2(3.14)(4.5)

C = 28.26

a scientist notes that the number of bacteria in a colony is 50.3 hours later, she notes that the number of bacteria has increas
sergejj [24]

It will take 5.83 hours for the bacteria to reach 1119.

<h3>What is exponential Growth ?</h3>

Exponential growth is when the quantity increases according to the function

P_t = P_0 e^{ kt}

It is given in the question that

Initial number of Bacteria is 50

After 3 hours the bacteria has increased to 80

The bacterial growth is an exponential growth

P_t = P_0 e^{ kt}

80 = 50 e^{ k * 3}

Applying log on both sides

1.6 = 3*k

k = 1.6/3

k = 0.533

if this rate of growth continues, how much more time will it take for the number of bacteria to reach 1119

1119 = 50e^{0.533* t}\\\\3.18 = 0.533 *t\\\\5.83 = t

Therefore it will take 5.83 hours for the bacteria to reach 1119.

To know more about exponential growth.
