Answer:
240.6 m²
Step-by-step explanation:
Mr samuel built a circular fenced-in section for some of his animals the section has a circumference of 55. What is the approximate area in square meters of the section? Use 22/7 for pie
Step 1
We have to find the radius of the circular fence
The circumference of a circle = 2πr
Circumference = 55m
Hence:
55m = 2 × 22/7 × r
55 = 44/7
r = 55 ÷ 44/7
r = 55 × 7/55
r = 8.75m
Step 2
We find the approximate area in square meters of the section.
Area of a circle = πr²
Area of the circle = 22/7 × 8.75²
Area of the circle = 240.625 m²
Approximately = 240.6 m²
Therefore, the approximate area in square meters of the section is 240.6m²
You can solve it with the numbers you already have.
so, 23 - 15 = 8
so 15 + 8 = 23
b is 8 (:
There is missing information about this question that I found online.
Given function is:
The question is:
<span>Is this exponential growth or decay? Explain using your understanding of the properties of exponents.
</span>This is an exponential decay.
In general, we can write down exponential functions like this:
Parameter a is the key parameter that will tell how exponential function behaves. If it is positive we have an exponential growth. If it is negative we can rewrite function like this:
We can notice that in this case, the denominator will exhibit exponential growth, in other words, the functions rapidly declines. This is an exponential decay.
Answer:
30
Step-by-step explanation:
30 * 2 is 60
60 - 10 is 50
