Top brown surface = \pi  r^{2} = 3.142 x 16 x 16 = 804.352 square inches

Side Brown surface = 2 \pi rh = 2 x 3.142 x 16 x 6 = 603.264 square inches

Side Green surface = 2 \pi rh = 2 x 3.142 x 16 x 8 = 804.352 square

Total Surface area = 804.352 + 804.352 + 603.264 = 2211.968 square inches

% that is green = 804.352 ÷ 2211.968 x 100% = 36.37%

Treat the ottoman as a cylinder.
area of the top surface is πr²=π*16²
The total lateral area (the side) is: π*d*h=2*16*π*(6+8)=28*16π (diameter is twice the radius, so d=2*16)
the area of the green part is: π*d*8=2*16**8π=16*16π
not including the bottom, the total area is the top plus the total side:16²π+16*28π=(16+28)*16π=44*16π

the percent of the green part is: 16²π/44*16π=16/44≈36%
Is 36% a choice?

valentinak56 [21]

Mr. and Mrs. Lorenzo have saved $38,430 for the home they want to buy

Information about the problem:

  • Initial cost = $213,500
  • Savings = 18%.
  • Final savings =?

To solve this exercise we have to apply the percentage formula:

Final savings = initial cost * savings / 100

Final savings = $213,500 * 18 / 100

Final savings = $213,500 * 0.18

Final savings = $38,430

<h3>What is a percentage?</h3>

Percentage is defined as the number that represents a ratio of a total that is divided by 100 equal parts. It is represented by the symbol %.

The first term is a(1) = -3
The recursive step is a(n) = a(n-1)+7 meaning "add 7 to each previous term to get the next term". This points us to the common difference d being 7

a1 = -3 
d = 7

an = a1 + d(n-1)
an = -3 + 7(n-1)
an = -3+7n-7
an = 7n-10

Answer: a_{n} = 7n-10 (it says an = 7n-10 if the image doesn't show up)
Note: the n starts at n = 1
