Answer:

  16.9 units

Step-by-step explanation:

Sometimes the easiest way to work these problems is to get a little help from technology. The GeoGebra program/app can tell you the length of a "polyline", but it takes an extra segment to complete the perimeter. It shows the perimeter to be ...

  14.87 + 2 = 16.87 ≈ 16.9 . . . units

_____

The distance formula can be used to find the lengths of individual segments. It tells you ...

  d = √((Δx)² +(Δy)²)

where Δx and Δy are the differences between x- and y-coordinates of the segment end points.

If the segments are labeled A, B, C, D, E in order, the distances are ...

  AB = √(5²+1²) = √26 ≈ 5.099

  BC = √(1²+3²) = √10 ≈ 3.162

  CD = Δx = 3

  DE = √(3²+2²) = √13 ≈ 3.606

  EA = Δy = 2

Then the perimeter is ...

  P = AB +BC +CD +DE +EA = 5.099 +3.162 +3 +3.606 +2 = 16.867

  P ≈ 16.9

MATH QUESTION!! PLEASE HELP
svlad2 [7]

bro i literally had the same question about this

you in honors or something? sry i only got A

I might have B later on or something

Answer:

A.

41.125π ≈ 129

149.875π ≈ 471

Step-by-step explanation:

Surface area of smaller ganza:

3.5/2 = 1.75 x 1.75 = 3.0625 x 3.14 = 9.61625 x 2 = 19.2325

1.75 x 10 = 17.5 x 3.14 = 54.95 x 2 = 109.9 + 19.2 = 129 (Rounded)

Surface area of larger ganza:

5.5/2=2.75 x 2.75 = 7.5625 x 3.14 = 23.74625 x 2 = 47.4925

2.75 x 24.5 = 67.375 x 3.14 = 211.5575 x 2 = 423.115 + 47.4925 = 471 (Rounded)

π

129/3.14 = 41.125

471/3.14 = 149.875
