If the radius of a circle is 3. 5 inches, its diameter is inches and its approximate area is square inches
Answer: 7 Inches
Explanation:
Diameter = 7 inches
Area of circle is 38.46 inches²
Step-by-step explanation:
Given :The radius of a circle is 3.5 inches.
We have to find its diameter and area.
Since diameter is twice of radius.
So radius = 3.5 inches
Diameter = 2× 3.5 inches = 7 inches
Area of circle =
Substitute, r = 3.5
Area of circle = (3.5)
Simplify , we have,
Area of circle = 12.25
Using π = 3.14
We have,
Area of circle = 38.465
Thus, Area of circle is 38.46 inches²

All of the following must be addressed in your response to receive full credit: a. Discuss the transfer of biomass when one organism eats another. Use your knowledge of digestion to discuss how food is broken down and used by the consumer. B. Explain what happens to the energy that is not transferred from one organism to another. C. Explain why there are typically fewer organisms at the top of an energy pyramid. D. Use specific numbers and calculations to support your explanation
The model here is not found here but matter and energy flow in the food pyramid from lower trophic levels to higher trophic levels.
What is a food pyramid?A food pyramid is a diagram that represents the trophic relationships between species in a given ecosystem.
Biomass can be transferred when one organism eats another because life forms are composed of macronutrients such as proteins, carbohydrates and fats (lipids).
Digestion is a metabolic process where larger macronutrients are degraded onto smaller components that can be used to build body structures.

Lesson 4 skills practice properties of similar polygons
Two polygons are similar if corresponding side lengths have equal scale factor
The polygons are not similar
How to determine if the polygons are similar?From the complete question, we have two polygons with the following corresponding side lengths:
5 and 812 and 1513 and 17Calculate the scale factor (k) using:
k = Polygon B/Polygon A
So, we have:
k = 8/5 = 15/12 = 17/13
Evaluate the quotients
k = 1.60 = 1.25 = 1.31
The factors are not equal i.e.
1.60 ≠ 1.25 ≠ 1.31
Hence, the polygons are not similar

When 70. G of li3n(s) (molar mass 35 g/mol) reacts with excess h2(g), 8. 0 g of lih(s) is produced. The percent yield is closest to
Answer:
25%
Explanation:
Li3N(s) + 2 H2(g) ⇄ LiNH2(s) + 2 LiH(s)
70 g Li3N x 1 mol Li3N/35 g = 2 mol Li3N
2 mol Li3N x 2 mol LiH/1 mol Li3N
= 4 mol LiH x 7.05 g LiH/1 mol LiH = 28.20
percent yield = actual yield/theoretical yield x 100
8 g / 28.20 g ≈ 28%
28% is closest to 25% ap classrom
When 70. G of li3n(s) (molar mass 35 g/mol) reacts with excess h2(g), 8. 0 g of lih(s) is produced. The percent yield is 25%.
What is the percent yield?The actual yield is calculated as the theoretical yield multiplied by 100 to get the percent yield. There are a variety of reasons why a chemical reaction's actual yield could be lower than its theoretical yield, and they will be covered in more detail in later chapters of the course.
Li₃N(s) + 2 H₂(g) ⇄ LiNH₂(s) + 2 LiH(s)
70 g Li₃N x 1 mol Li₃N/35 g = 2 mol Li₃N
2 mol Li₃N x 2 mol LiH/1 mol Li₃N
4 mol LiH x 7.05 g LiH/1 mol LiH = 28.20
Percent yield = actual yield/theoretical yield x 100
8 g / 28.20 g = 28%
28% is closest to 25%
