Answer:

2623.6144m²

Step-by-step explanation:

Total Surface Area of a Square Pyramid

a * (a + √(a² + 4h²))

where,

a = area of base

h = height

Using the formula above

a * (a + √(a² + 4h²))

data given :

a = 36

h = 4

a * (a + √(a² + 4h²))

T.S.A. = a * (a + √(a² + 4h²))

Inputting values

T.S.A. = 36 * (36 + √(36² + 4 * 4²))

T.S.A. = 36 * (36 + √(36² + 4 * 16))

T.S.A. = 36 * (36 + √(36² + 64))

T.S.A. = 36 * (36 + √(1296 + 64))

T.S.A. = 36 * (36 + √(1360))

T.S.A. = 36 * (36 + 36.87817782917154)

T.S.A. = 36 * (72.87817782917154)

T.S.A. = 36 * 72.8782

T.S.A. = 2623.614401850175

Therefore Total Surface Area (T.S.A.) is 2623.6144m²

Answer:

96 units²

Step-by-step explanation:

Base area = side² = 36

Each side = 6 units

Surface area includes 1 square and 4 identical slant triangles

Area of square: 36

height of a slant triangle:

height² = 3² + 4² = 25

height = 5

Area of each slant triangle = ½×6×5 = 15

Total SA = 36 + 4(15)

= 36 + 60 = 96 units²

Based on the data set shown, which of the following is a true statement?
patriot [66]
The mean, median, and mode are equal to 1. So among the choices, the first one is correct - mean = mode

Mean - an <em>average </em>of the given set of number; to find this, add the numbers and divide it by 11 (the number of given data)
   = (-1 + -1 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3) / 11
   = 1

Median - the <em>middle or center</em> of the given set; to find this, arrange the numbers in numerical order, then get the center or middle number as the median
   = <span>-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
   = [</span><span>-1, -1, 0, 1, 1,] <u>1</u>, [1, 2, 2, 2, 3]

Mode - is the value that occurs most of the time in the given set; so obviously <em>number 1 occurred four times</em> so 1 is our mode
