Answer:
3.14 units²
Step-by-step explanation:
Area=πr²
Where π=3.14, r=1 unit
=(3.14)(1)²
=(3.14)(1)
=3.14 units²
Answer: m=n=3
Step-by-step explanation:
Reflecting across the y=0, in other words, the x-axis, means

So, 
This gives us the system

46! Because 5 times 3 is 15 and the two big rectangles are equal, that’s 15+15. (30) 5x1 is 5 and THERES two equal things like that so 5+5 (10). 3x1 is 3 and THERES also two equal things so add 3+3. (6) add 30+10+6 which makes 46! :)
The estimate closest to an average person's weight is 80kg
<h3>How to determine the estimate?</h3>
The weights are given as:
8 kg, 80 kg and 800 kg
To answer this question, I will assume that a person means an adult
An adult that weighs 8 kg is very much under weight
Because the average weight of a person is around 60 to 90 kg
Hence, the estimate closest to an average person's weight is 80kg
