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}.

Leni [432]
The answer is 98 degrees relative to the axis(probably u or v axis ) due to the fact that complementary angles are 90 degrees or it could be 8 degrees if you take the u or v axis as a constraint axis
