Answer: The length of radius of a circular pool is 7 meters
Step-by-step explanation:
Given that the circumference of a circular pool cover is about 88 meters
To find the length of radius
As we know circumference of a circle is given by
where C is circumference , and r is radius of the circle
Now as according to question we have
![88= 2\pi r\\\\\Rightarrow 88= 2\times \dfrac{22}{7} r\\\\\Rightarrow r= \dfrac{88\times 7}{2\times 44} = 7 m](https://tex.z-dn.net/?f=88%3D%202%5Cpi%20r%5C%5C%5C%5C%5CRightarrow%2088%3D%202%5Ctimes%20%5Cdfrac%7B22%7D%7B7%7D%20r%5C%5C%5C%5C%5CRightarrow%20r%3D%20%5Cdfrac%7B88%5Ctimes%207%7D%7B2%5Ctimes%2044%7D%20%3D%207%20m)
Hence,the length of radius of a circular pool is 7 meters
Step-by-step explanation:
Total number of legs = 80
So if there are 10 mammals so there legs = 40
And the no of resident birds should be twice
