Answer:
[tex]A=5024\ cm^2[/tex]
Step-by-step explanation:
Father will make an ornamental fish pond. The pool is circular with a diameter of 80 cm, the area of land needed to make a pool is ??
The diameter of a circular pool, d = 80 cm
It means that,
Radius, r = d/2
r = 40 cm
We need to find the area of the land needed to make a pool. The area of a circular path is given by :
[tex]A=\pi r^2[/tex]
Put the values in the above formula.
[tex]A=3.14\times (40)^2\\\\A=5024\ cm^2[/tex]
So, it will require [tex]5024\ cm^2[/tex] area of land to make a pool.
