Answer:
Step-by-step explanation:
Volume of cylinder = πr²h
Volume of cone = πr²h/3
Volume of cylinder is not used by cone = ⅔πr²h = ⅔(3.14)(3^2)(8) = 150.72 sq in
Answer: Concave down
Explanation:
An example is shown below. We have the concave down parabola marked in red. The trapezoidal sum is in blue. The three trapezoids combine to something just a bit smaller than the true area under the curve from x = -2 to x = 1. Therefore, this trapezoidal sum is an underestimate of the true area under the curve.
Every part of each trapezoid is completely below the red curve. In other words, no part of the blue pieces spill above the parabola.
Answer:
Below.
Step-by-step explanation:
tan < XYZ = opposite/adjacent
= 8/20 = 0.4.
XYZ = 21.8 degrees to 3 s f.
Equation A:= True and has an infinite number of solution and B: is False no solution exists thus d: is your Answer.
