Question

Mr. McCoy is planning to install a circular pool. The circumference of the pool is 25 feet. What is the area sow your work

Answer 1

Answer: Area of circular pool is 47.8 ft².

Step-by-step explanation:

Since we have given that

Circumference of the pool = 25 feet

Let the radius of circular pool be 'r'.

As we know the formula for "Circumference of pool":

$C=2\pi r\\\\25=2\times \frac{22}{7}\times r\\\\\frac{25\times 7}{2\times 22}=r\\\\3.9\ ft=r$

So, Area of circular pool will be

$Area=\pi r^2\\\\Area=\frac{22}{7}\times 3.9\times 3.9\\\\Area=47.8\ ft^2$

Hence, Area of circular pool is 47.8 ft².
