A. True...... ............ .......
Exactly what you just said 1:19
B) 28.26 squared feet.
To fine area, you need the radius. radius is half of diameter. half of 6 is 3. A=πr2=π·32≈28.27433
So, given a quadratic function, y = ax2<span> + bx + c, when "a" is positive, the </span>parabola<span> opens upward and the vertex is the </span>minimum<span> value. On the other hand, if "a" is negative, the graph opens </span>downward<span> and the vertex is the </span>maximum<span> value. To put it in complicated terms. Or when A is positive the graph is shaped like a U but if A is negative the graph is an upside down U
