During a research experiment, it was found that the number of bacteria in a culture grew at a rate proportional to its size. at 66: 00 am there were 3 comma 0003,000 bacteria present in the culture. at noon, the number of bacteria grew to 3 comma 7003,700. how many bacteria will there be at midnight?

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
