First, let's find the area! The formula to find the area of a circle is πr²
πr²
3.14 · 4²
50.24 yds²
Now let's find the circumference. The formula for this is 2πr
2πr
2 · 3.14 · 4
25.12 yds

Answer:
No extraneous solution
Step-by-step explanation:
We have the logarithmic equation given by,
![\log_{2}[\log_{2}(\sqrt{4x})]=1](https://tex.z-dn.net/?f=%5Clog_%7B2%7D%5B%5Clog_%7B2%7D%28%5Csqrt%7B4x%7D%29%5D%3D1)
i.e. 
i.e. 
i.e. 
i.e. 
i.e. 
i.e. 
So, the solution of the given equation is x=4.
Now, as we domain of square root function is x > 0 and also, the domain of logarithmic function is
.
Therefore, the domain of the given function is x > 0.
We know that the extraneous solution is the solution which does not belong to the domain.
But as x=4 belongs to the domain x > 0.
Thus, x = 4 is not an extraneous solution.
Hence, this equation does not have any extraneous solution.

56,000÷2 = 28,000
14,000÷2 = 7,000
28,000/7,000 = 28/7
28 ÷ 7 = 4
---- -----
7 ÷7 = 1
4:1
