Answer:

C. 6m

Step-by-step explanation:

The formula for the volume of a cone: V = πr²h/3

Use this formula to solve for the height (isolate h).

226 = (3.14)(6)²h/3 (Given)

226 = (3.14)(36)h/3 (Squared 6)

226 = 113.04h/3 (Multiplied like terms)

678 = 113.04h (Multiplied 3 on both sides)

h = 5.997876858 ≈ 6 (Divided 113.04 on both sides)

What two-dimensional figure will result from slicing this rectangular pyramid parallel to the base?

andreev551 [17]

Answer: The answer is D. Trapezoid.

Step-by-step explanation: As shown in the attached figure, a rectangular pyramid ABCDE is drawn. We are slicing this rectangular pyramid parallel to the base BCDE at the points F, G, H and I.

We can clearly see from the figure that upper half of the sliced figure will be similar to the pyramid BCDE and the lower sliced figure will be a trapezoid. These are the three-dimensional figures.

Also, the sliced two-dimensional figure FGHI will be a rectangle, because

the pyramid is a rectangular one and so, FI=GH, FG=HI and all the angles are right angles.

Thus, the resulting two-dimensional figure will be a rectagle.
