Answer:
153.86 square feet
Step-by-step explanation:
The formula for the area of a circle is : [tex]\pi *radius^2[/tex]
To work this out you would simply multiply pi by the radius of 7 squared, this gives you 153.86. This is because if you were to substitute the values into the formula you would also get the same answer.
1) Multiply pi by 7 squared.
[tex]\pi *7^2=153.86 feet^2[/tex]
In this question pi is as 3.14
