Answer:
He will need 39 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:
Using the value π = 3.14.
[tex]Area=\pi r^2\\\\Area=3.14\times 5^2\\\\Area=3.14\times 25\\\\Area=78.5\ feet^2.[/tex]
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:
[tex]\frac{Area\ of\ the\ circular\ fountain}{Area\ each\ brick\ covers}[/tex]
[tex]=\frac{78.5}{2}[/tex]
[tex]=39.25.[/tex]
Approximately 39 bricks he need to buy.
Therefore, he will need 39 bricks to buy.
