Given:
Diameter of a circle = 2 feet
To find:
The area of a circle.
Solution:
We know that, area of a circle is
[tex]A=\pi r^2[/tex]
Where, r is the radius of the circle.
Diameter of a circle = 2 feet
So, radius of the circle = [tex]\dfrac{2}{2}=1[/tex] feet
Putting r=1 and [tex]\pi=3.14[/tex] in the above formula, we get
[tex]A=(3.14)(1)^2[/tex]
[tex]A=(3.14)(1)[/tex]
[tex]A=3.14[/tex]
Therefore, the area of the circle is 3.14 sq. feet.
