Answer:

Step-by-step explanation:
The pool are is divided into 4 separated shapes: 2 circular sections and 2 isosceles triangles. Basically, to calculate the whole area, we need to find the area of each section. Due to its symmetry, both triangles are equal, and both circular sections are also the same, so it would be enough to calculate 1 circular section and 1 triangle, then multiply it by 2.
<h3>Area of each triangle:</h3>
From the figure, we know that <em>b = 20ft </em>and <em>h = 25ft. </em>So, the area would be:

<h3>Area of each circular section:</h3>
From the figure, we know that
and the radius is
. So, the are would be calculated with this formula:

Replacing all values:

Remember that 
Therefore, 
Now, the total are of the figure is:

Therefore the area of the symmetrical pool is 
One hundred and twenty thousand
Answer: The circumference of the circle is 53.38 cm.
Step-by-step explanation:
Circumference of the circle is the distance around the circle.
Formula used:

Where,
C is circumference of circle
r is radius of circle
Given:
Radius of circle = 8.5 cm
Now putting all the given values in the above formula, we get:

Therefore, the circumference of the circle is 53.38 cm.
