Answer:
C = pi sqrt(x)
Step-by-step explanation:
The area of a square is x
A = s^2 where s is the side length
x = s^2
Take the square root of each side
sqrt(x) = s
This would be the diameter of the inscribed circle
The circumference of a circle is given by
C = pi d
C = pi sqrt(x)
Answer:
The problem of <u>(Choice B)</u> could be solved with the expression (4+2)\times4.
Step-by-step explanation:
Given:
Which problem could be solved with the expression (4+2)\times4?
(Choice A) A Bobby sold 4 baseball cards on Monday. He then sold 2 more on Tuesday. He sold the same amount for 2 weeks. How many did he sell?
(Choice B) B Danny ran 4 miles in the morning and 2 miles in the afternoon. He did this for 4 days. How many miles did he run?
(Choice C) C Suzanne makes wooden dolls. She made 2 in the morning and 2 in the afternoon. She did this for 4 days. How many dolls did she make?
Now, to choose one answer:
The problem of (Choice B) could be solved with the expression (4+2)\times4.
(Choice B) Danny ran 4 miles in the morning and 2 miles in the afternoon. He did this for 4 days. How many miles did he run?
<em>Danny ran 4 miles in the morning and 2 miles in the afternoon.</em>
<em>So, adding both the miles we get:</em>
<em /><em />
<em>Now, he did this for 4 days.</em>
<em>Thus, multiplying by 4 we get:</em>
As, the other choices doesn't match the expression.
Therefore, the problem of (Choice B) could be solved with the expression (4+2)\times4.
