Answer:
49π ft²
Explanation:
The area for a circle is A=πr² (Area=pi times radius squared)
and d=2r (diameter = 2 times the radius)
So, if we want to find area using the radius, we can get rearrange the equation d=2r to get r= d/2
r=d/2
r=14/2
r=7 ft
Then we can plug that answer into the area equation.
A=π×7²
7 squared is 49 so
A=49π ft²
