HELP ASAP 20PTS! Sierra is constructing an inscribed square. Keaton is constructing an inscribed regular hexagon. In your own words, describe one difference between Sierra's construction steps and Keaton's construction steps.

Sierra needs to construct the perpendicular bisector of a diameter, and Keaton does not.

Sierra needs to construct the perpendicular bisector, and Keaton no

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
