Answer:
Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. The formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.
Step-by-step explanation:
Answer:
Between 150 and 200 seeds will sprout
Answer:
Step-by-step explanation:
1. Perfect square trinomials, are 2nd degree polynomials, of the form so that , which can be written as perfect squares.
2. For example
3. Thus are perfect square trinomials.
4.
5. In the first case -b=20, so b=-20. In the second case, -b=-20, so b=20.
6. b∈{-20, 20}
The answer is: [B]: 9.61 and 10.24 .

[Note: This is based on the assumption that the expression in the problem given is: "(π) squared"; or: "π² " — [and NOT: "(π*2)"; or, "(2*π)".]

Explanation:
______________________________________
Let us assume the expression in the problem means:
"(π) squared" or, "π² " {"pi squared"; or, "pi to the second power"}.
___________________________________
Then, π² = (3.1415926535897932) ²
= 9.8696044010893583772
___________________________________
Even if one uses "3.14" for "π" ; since π ≈ 3.14; then:
Then, π² ≈ (3.14)² ; and: (3.14)² = 9.8596
___________________________________
Both methods result is 9.8....; which corresponds with:
Answer choice: [B]: 9.61 and 10.24 .
