Annie is filling flower pots with soil. Each flower pot is shaped like a cylinder. Just like the one here below. The radius is 2
Anna [14]

Answer:

  • None

Step-by-step explanation:

<u>Given:</u>

  • Radius r = 2 in =  2*2.54 cm = 5.08 cm
  • Height h = 6 in = 6*2.54 cm = 15.24 cm
  • Volume of soil V = 200 cm³

<u>Find the volume of one pot:</u>

  • V = πr²h
  • V = 3.14*5.08²*15.24 = 1234.92 cm³

From the number above we see the volume of each pot is greater than the volume of soil Ann has, so she can't fill any.

The answer is zero

<em>Note. If the volume unit of soil was in³ the answer would be different</em>

If we wanted to prove quadrilateral MNOP was a parallelogram, which method below would not work?
rjkz [21]

Answer:

The correct option is 4.

4) Doing two distance formulas to show that adjacent sides are not the same length.

Step-by-step explanation:

Parallelogram is a quadrilateral which has opposite sides equals and parallel. Example of a parallelogram are rhombus, rectangle, square etc.

We can prove that a quadrilateral MNOP is a parallelogram. If we find the slopes of all four sides and compare those of the opposite ends, same slopes would indicate the opposite sides are parallel, hence the quarilateral is a parallelogram. We can also find the distance of two opposing sides, and slopes of twp opposing sides to determine whether it is a parallelogram or not. The most difficult approach is that diagonals bisect each other at same point.

However, using only two distance formulas will not give us enough information to determine whether a side is parallel or not.
