Answer:

125 square meters

Step-by-step explanation:

Decomposition: Breaking up the shapes, finding their areas individually, and adding up their areas.

Area of a triangle: base * height * 0.5

First, let's look at the area of the top left triangle. The base is 5, while the height is 17. Thus, its area is

5 * 17 * 0.5 = 42.5

The bottom left triangle has a base of 5, and a height of 17, so its area is

5 * 17 * 0.5 = 42.5

The top right triangle has a height of 8 and a base of 5, so its area is

5 * 8 * 0.5 = 20

The bottom right triangle has a height of 8 and base of 5, so its area is

5 * 8 * 0.5 = 20

Now, add up all the areas.

42.5 + 42.5 + 20 + 20 = 125

Thus, the answer is 125 square meters.

I hope this helps! Feel free to ask any questions!

2 ft
sdas [7]

Answer:

88/7 ft = 12.6 ft (nearest tenth)

Step-by-step explanation:

Circumference of a circle = 2\pir

<u>Radius of inner circle</u>

Given:

  • circumference of inner circle = 22ft
  • \pi = 22/7

⇒ 22 = 2 x (22/7) x r

⇒ r = 3.5

So the radius of the inner circle is 3.5 ft

<u>Radius of outer circle</u>

If the distance between the inner circle and the outer circle is 2 ft, then the radius of the outer circle = 3.5 + 2 = 5.5

<u>Circumference of outer circle</u>

Therefore, circumference of outer circle:

=  2 x (22/7) x 5.5

= 242/7 ft

<u>Difference between circumferences</u>

Difference = outer circle circumference - inner circle circumference

                  = 242/7 - 22

                  = 88/7 ft

                  = 12.6 ft (nearest tenth)

Given the sequence rn defined recursively below, find r3. r1rn=2=−rn−1+n−2
kifflom [539]

Answer:

r_3=3

Step-by-step explanation:

Given:

r_1=2\\r_n=-r_{n-1}+n-2

We want to find the value of r_3 .

\\r_2=-r_{2-1}+2-2\\r_2=-r_1\\r_2=-2\\\\r_3=-r_{3-1}+3-2\\r_3=-r_{2}+1\\r_3=-(-2)+1\\r_3=2+1\\r_3=3

An aquarium is a cylinder with a diameter of 203 feet and a height of 25 feet. What is the volume of the aquarium
lilavasa [31]

Volume formula for a cylinder is pi*r^2*h

h=height=25 feet

r=radius=101.5

Radius is half of the diameter.

Plug those numbers in: pi*101.5^2*25= 809136.822886= 8.09*10^5 hopefully this helps! ^-^
