Answer:

He will need 39 bricks to buy.

Explanation:

Given:

Radius of the circular fountain = 5 feet.

Each brick covers an area = 2 ft².

Now, to find the bricks he will need to buy.

So, we get the area of circular fountain by putting formula:

Using the value π = 3.14.


Area=\pi r^2\\\\Area=3.14* 5^2\\\\Area=3.14* 25\\\\Area=78.5\ feet^2.

Area of the circular fountain = 78.5 feet².

According to question:

Each brick covers an area = 2 ft².

Now, to get the number of bricks he will need to buy:


(Area\ of\ the\ circular\ fountain)/(Area\ each\ brick\ covers)


=(78.5)/(2)


=39.25.

Approximately 39 bricks he need to buy.

Therefore, he will need 39 bricks to buy.
