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.
Answer:
18
Step-by-step explanation:
Total Surface Area of the Metal Sheet =
Given a cylinder with diameter 3 Inch and height
To determine how many whole cans can be made, the first step is to find the total surface area of each of the cylindrical can.
Total Surface Area of a cylinder =
- Radius =3÷2=1.5 Inch
- Height of the can =
<u>Total Surface Area of each can </u>
<u>Number of Cans that can be Made </u>
To determine this, we divide the total surface area of the metal sheet by the total surface area of each can.
Number of Cans=Total surface area of the metal sheet÷Total surface area of each can.
Therefore, the company can make 18 whole cans from each sheet of metal.
Answer:
∠ XAZ = 50°
Step-by-step explanation:
The measure of the circle = 360°
Given arc XYZ = 230°, then
arc XZ = 360° - 230° = 130°
The tangent- tangent angle XAZ is one half the difference of the intercepted arcs, that is
∠ XAZ = (230 - 130)° = 0.5 × 100° = 50°
