Answer:

The expression provided by the area (square meters) is given by: $A(t) = pi \frac{100t^{2} }{9}$ .

Step-by-step explanation:

The area of the algae colony is a function of the radius r (meters), so $A(r) = \pi r ^ 2$ .

The radius of the circle formed by the algae colony is a function of time t (in minutes), so $M (t) = \frac{10t }{3}$ . So,

$A(r) = \pi r ^ 2$ [Substituting the expression for radius]

$A(t) = pi (\frac{10t }{3})^{2} = pi \frac{100t^{2} }{9}$

Then the expression provided by the area (square meters) is given by: $A(t) = pi \frac{100t^{2} }{9}$ .

Perimeter = 4×
Where x = 5/7
4* 5/7
p= 20/7
The answer will be a mixed fraction
p= 2 6/7 units

Hope that helps!

The best scale would probably be going by 10s. You should start at around 80 and go up to 160.
