A conjecture and the paragraph proof used to prove the conjecture are shown.
aleksklad [387]

Observe the figure given.

Let us complete the given paragraph:

It is given that E is the midpoint of DF. So, DE \cong EF by the definition of midpoint.

As, midpoint divides the line segment into two equal halves.

Therefore, DE  =EF by the segment congruence postulate. DE+EF = DF by the segment addition postulate and so DE+DE = DF by substitution.

Segment Addition Postulate states that given 2 points P and Q, a third point S lies on the line segment PQ if and only if the distances between the points satisfy the equation PS + SQ = PQ.

Simplifying gives 2DE = DF.

kap26 [50]

She needs to buy 6 bags of soil. the correct option is B

Given

Caisha has a circular garden with a radius of 4 ft.

She needs to put a layer of soil on top. e

Each bag of soil covers 9.42 square feet.

<h3>What is the radius of a circular garden?</h3>

The radius of the circular garden is equal to the pie times of the square of the radius.

The radius of the circular garden is;

\rm Area = \pi r^2\\\\Area = 3.14 \times (4)^2\\\\ Area = 3.14\times 16\\\\Area =50.24

Therefore,

The number of bags of soil will she need to buy is;

\rm = \dfrac{Area }{Soil \ covers}\\\\= \dfrac{50.24}{9.42}\\\\= 5.33\\\\= 6 \ bags \ apporx

Hence, she needs to buy 6 bags of soil.
