Answer:
He will need <u>39</u> bricks to buy.
Step-by-step 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:
<em>Using the value π = 3.14.</em>
<em>Area of the circular fountain = 78.5 feet².</em>
<em>According to question:</em>
<em>Each brick covers an area = 2 ft².</em>
Now, to get the number of bricks he will need to buy:
<em>Approximately 39 bricks he need to buy.</em>
Therefore, he will need 39 bricks to buy.
