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.
You need to determine what is happening in the situation maybe? If the number is increasing then it would be + or x and if they were decreasing it would be / or -
Answer:
Unnnnnnnnnnnnnnnnnnnnnnnnbnbnnnn
The answer is -2 (negative two) yards away from the goal line (meaning that the ball is in the end zone or past the goal line).
