First, we need to think about what we're actually solving for: the area of the path. To find this, we can find the area of the whole thing, minus the area of the pool.
The diagram would look something like the picture I attached. We know that to find the area of a circle, you do πr^2. The radius is half of the diameter, so halve the diameters:
22/2 = 11 yards
32/2 = 16 yards
Then solve for the area of both circles.
π
![11^{2}](https://tex.z-dn.net/?f=%2011%5E%7B2%7D%20)
![= 121](https://tex.z-dn.net/?f=%3D%20121)
π ≈ <span>380.13 (area of the pool)</span>
π
![16^{2}](https://tex.z-dn.net/?f=%2016%5E%7B2%7D%20)
![= 256](https://tex.z-dn.net/?f=%3D%20256)
π ≈ <span>804.25 (area of the whole thing)
</span>
Next, subtract the area of the pool from the area of the whole thing to find the area of the walkway:
![804.25 - 380.13 = 424.12](https://tex.z-dn.net/?f=804.25%20-%20380.13%20%3D%20424.12)
(area of the walkway)
Finally, divide the area of the walkway by 6 to see how many gallons of paint you'll need:
424.12 ÷ 6 ≈ 70.69
So you'll need 71 gallons of paint!
Hope I helped and let me know if you have any questions :)
Answer:
129.89 m²
Step-by-step explanation:
Area of a circle of radius r is A = πr².
If r = 6.43 m, then A = π(6.43 m)² = 129.89 m²
The net cannot be folded to form a pyramid because the faces that are not a base are not all triangles
If you fold this net up, you will get a triangular prism, NOT A PYRAMID.
A pyramid can have ANY polygon as its base, as long as all the other rest of the shapes are triangles.
Depending on the base, the number of triangles in a net of a pyramid must match the number of sides its particular base has.
For example, if you have a square pyramid turned into a net:
The base is a square (4 sides)
There should be 4 triangles on each side.
Because a pyramid is where all the triangles must meet up at a point.
Hope this helps!
Answer:
do you have a picture?
Step-by-step explanation:
I could use a picture
When we choose to do cosine we do adjacent/hypotenuse so it would be...
Cos(32)= x/23
Than solve for x
X= 19.18 o 19.2
