Answer: 2625
Let’s say you multiply 5 giraffes by 75 pounds = 375lbs 5 giraffes eat a day multiply the 5 giraffes and they answer should be 2625lbs
The relationship between the rates of change can be found by taking the derivative of area with respect to time.
... a(t) = π·r(t)²
... a'(t) = 2π·r(t)·r'(t)
At the time of interest, we have
... a'(t) = 2π·(6 ft)·(5 ft/min) = 60π ft²/min
The rate of change of area at that time is 60π ≈ 188.5 ft²/min.
KMN = 90° (tangent perpendicular to radius)
Using Pythagoras Theorem,
√(8^2 + 6^2) = √(100) = 10
Therefore KN = 10km
The answer is f(x)=3 or y=3
