Step-by-step explanation:
When finding the area of a circle you have to use the formula
Area= Pie x radius^2
Radius=8.5
So you have to plug that into the equation.
8.5x8.5=72.25
72.25x3.14=226.87
So Area is 226.87
So your answer is B

Answer:
Option C. −4≤t≤−3
Step-by-step explanation:
we have

This is the equation of a vertical parabola written in vertex form
The parabola open upward (the leading coefficient is positive)
The vertex is a minimum
The vertex is the point (-3,5)
The function is increasing in the interval [-3,∞)
The function is decreasing in the interval (-∞,-3]
The function will have a negative average rate when the function will be decreasing
therefore
the answer is option C
