Answer:
261 cm²
Step-by-step explanation:
To find the surface area of a square pyramid, you must first recognize all of the shapes.
There are four triangles and one square.
- To find the area of a square, multiply the side by itself twice.
- To find the area of a triangle, multiply the base and the height, then multiply the product by 1/2.
The triangles have a base of 9 and a height of 10.
Multiply the product by 1/2.
There are four triangles.
The area of all three triangles is 180 centimeters; the area of a single triangle is 45 centimeters.
There square has sides of 9 centimeters.
The area of the square is 81 centimeters.
Lastly, we add the areas of the shapes.
Therefore, the surface area of this square prism is 261 cm².
You can use this layout to find the surface area of a square pyramid.
Step-by-step explanation:
f(x)=2x+1
g(x)=2x-7
now,
- f-g(x)=f(x)-g(x)
- 2x+1-2x+7
- 8
(f-g)(x)=8
hope it helps.
Answer:
<h3>
Cristiano walked farther</h3><h3>
In 1 day: Lionel walked 1.8 mile</h3><h3>
Cristiano walked 1.875 mile</h3>
Step-by-step explanation:
2/6 = 1/3 so we just need to know what is more 3/5 or 5/8
3/5 = (3•8)/(5•8) = 24/40
5/8 = (5•5)/(8•5) = 25/40
25 > 24 so 5/8 > 3/5
so <u>Cristiano walked farther</u>
They walk for 1/3 of a day so in a whole day they walk three times the distance
3/5 • 3 = 9/5 = 1 4/5 = 1.8 mile
5/8 • 3 = 15/8 = 1 7/8 = 1.875 mile
