Step-by-step explanation:
the volume of a cylinder is as for any other regular 3D object :
ground area ×height
the ground area of a cylinder is a circle, so it is
pi×radius² × height
the radius is always half of the diameter (of the diameter is airways twice the radius).
radius = 6/2 = 3 ft.
the volume is then
pi × 3² × 9 = pi × 9 × 9 = pi × 81 ft³
so, the answer is 81pi ft³.
Answer: A
<u>Step-by-step explanation:</u>
x² + Mx + 18
∧
1 + 18 = 19 or -1 + -18 = -19
2 + 9 = 11 or -2 + -9 = -11
3 + 6 = 9 or -3 + -6 = -9
M can be +/- {19, 11, or 9}.
