Answer:
207 m².
Step-by-step explanation:
To find the surface area of the model, the area of the square base as well as the triangular sides will need to be found.
To find the area of the base, we can simply use the formula: A = s².
If s = 9, then:
A = 9²
A = 81. This is the area of the base.
To find the area of a triangular side, use the formula: A = 1/2(bh). b = 9, and h = 7.
Plugging these in get:
A = 1/2(7 · 9)
A = 1/2(63)
A = 31.5.
Since there are 4 sides to the base, this means that there are 4 triangular sides. Multiply the area of one triangle by 4, resulting in:
31.5 ×4 = 126.
Add up the area of the base and lateral parts of the pyramid, which equals:
81 + 126 = 207 m².
The answer is 2 be cause it is the only number that will go into both of them
You've certainly tried hard to describe it in enough detail so that
it can be answered without seeing the diagram. Sadly, it's not
enough.
We still don't know what's tangent to what, where point 'C' is, or
how any of this relates to a circle. You'll have to figure out some
way or us to see the diagram.
Answer:
52 ft^2
Step-by-step explanation:
To find the area you just multiply 13 feet (length) by 4 feet (width). This gives you 52 feet squared because we are dealing with area and square feet.
the value of x is 20
