Answer:
28.27 ft²
Explanation:
Area of the circle is equal to πr².
Where r is the radius.
π(3)²
9π = 28.274334
The area of the circle is 28.27 ft² approximately.
see below
The area of a circle is given by
A = pi r^2
A = pi (3)^2
A = 9pi
Letting pi be approximated by 3.14
A = 9 * 3.14
A=28.26 ft^2
If we use the pi button
A = 28.27433388 ft^2
