It depends what your trying to get close to. If your trying to get close to a number that is easier to work with 1 4/8 is good because its the same as 11/2 but the closest whole number is 1.

The area A(r)(in square meters) of a circular algae colony with radius r meters is given by A(r)=pir^2. Basically that's A(r)= p

Taya2010 [7]

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: $A(t) = pi \frac{100t^{2} }{9}$ .
