Aculture started with 6000 bacteria after 2 hours it grew to 7800 bacteria predict how many bacteria will be present after 15 hours

For bacterial growth, the kinetics follows the first order reaction whose equation is:

ln C = lnC0 + kt, where C and C0 are the population of bacteria after and at the start of time, respectively. The reaction constant is denoted as k.

We substitute C0 = 6000, C = 7800 and t=2 hours to determine k.

ln 7800 = ln(6000) + k(2)
k = 0.1312

Since we already know k, we use this value to find C when t=15 hours

ln C = ln(6000) + 0.1312(15)
C = 42,938

Thus, after 15 hours, the population of bacteria becomes 42,938.

answer:answer:

c = 32 * pi or approximately 100.48

step-by-step explanation:

the formula for circumference is

c = 2*pi*r

we know the radius is 16

c = 2*pi*16

c = 32 pi

or if we approximate pi as 3.14

c = 32 *3.14

   = 100.48
