C) Third figure

a) The height is the segment that goes vertically upward from the center of the base to the apex of the pyramid, i.e.  q  .

The apex is the point where the three leaned edges intersect each other.

b) The side length is the measure of the edge of the base, i.e.  r .

When the base of the pyramid is a square the four edges of the base have the same side length.

D) Fourth figure

1. Formula

The volume of a square pyramide is one third the product of the area of the base (B) and the height H).

2. Data:

3. Calculations

a) Calculate the area of the base.

The base is a square of side length equal to 11 cm:

b) Volume of the pyramid:

1. 953.775 cm³

2. 18,086.4 yd³

3. height: q ; side: r

4. 726 cm³

Step-by-step explanation:

1. Volume = pi × r² × h

= 3.14 × (9/2)² × 15

= 953.775 cm³

2. Volume = pi × r² × h

= 3.14 × 12² × 40

= 18086.4 yd³

3. height: q ; side: r

4. Volume = ⅓ base area × height

= ⅓ × 11² × 18

= 726 cm³

It is non-constant variable polynomial with in depth coefficients and an in depth root.
