Answer: 1,170ft^2

Step-by-step explanation:

We know that the area of the living room can be calculated with the formula for find the area of a rectangle. This formula is:

A_1=l_1*w_1

Where:

l_1 is the lenght  of the original living room, and  w_1 is the width of the original living room.

If he creates the addition that causes the dimensions to triple, then the new area of Garrett’s living room is:

A_2=(3l_1)(3w_1)\\A_2=(3*13ft)(3*10ft)\\A_2=1,170ft^2

Let's turn this sentence into an equation:

8n = -n + 36

Then solve:

9n = 36 => n=4

How do you answer the picture below?
3241004551 [841]

Answer:

42cm²

Step-by-step explanation:

because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²

Find the total surface area of the following cone. Leave your answer in terms of pi.
kramer

Answer:

90π cm²

Step-by-step explanation:

Given: Radius of circular base= 5 cm

           height= 12 cm

   

Now finding the surface of cone.

Formula; Surface area of cone= \pi rl+ B

Where; r= radius

l= slant height

B is the area of base, which is circle.

Area of circle (B)= πr²

Area of circle (B)= \pi \times 5^{2} = 25\pi

∴ Area of circle (B)= 25\pi

Finding slant height (l)

Formula; l= \sqrt{r^{2}+h^{2}  }

⇒l = \sqrt{5^{2}+12^{2}  } = \sqrt{25+144 }

∴ l= \sqrt{169} = 13\ cm

Next, using the formula for finding surface area of cone.

Surface area of cone= 5\times 13\times \pi + 25\pi

⇒ Surface area of cone= 65\pi +25\pi = 90\pi

∴ Surface area of cone= 90π cm²
