The exponential equation for the growth is f(x)=57 where x is the number of days and the population on 21st march is 2069983.5 of microbes.
Given:
Days population
0 57
1 95
5 700
10 8525
We have to form exponential equation which shows the growth of microbes.
We know that exponential equation which shows the sum is as under:
f(x)=P where r is the rate of growth and x is the number of days, months or years depending on how things grows.
In the question when x=0 population is 57.
f(0)=57
P=57
P=57
When x=1, population is 95.
f(1)=95
P=95
57 =95
57=95/----1
when x=5,population is 700.
f(5)=700
P=700
57=700
57=700/-----2
Equating 1&2
95/=700/
=7.36
=7.36
=
equating both sides
4r=2
r=0.5
put the value of t=21 in the exponential equation
f(21)=57
=57
=57*36315.5
=2069983.5
Hence the population on 21st march is 2069983.5.

The Reuleaux triangle is shown in the attached figure
we know that
the area of a Reuleaux triangle is equal to
where
r=18.6/2--------> r=9.3 m
so
therefore
the answer is
61 m²
