Determine the area of the unshaded region

Answer:
A= 28.27 ft
Step-by-step explanation:
The unshaded area is a circle.
the formula for the area of a circle is
A= pi x r^2
A= pi x 3^2
and that all comes out to 28.27 ft
you have a lot of these hmm
answer
28.27
Step-by-step explanation:
formula is
pi times r squared
so
r times r
then multiply that with pi
so
r is 3 (halfway through the circle)
so
3 x 3 which is 9
then
multiply 9 with pi
pi is 3.14
so
9 times 3.14
which is
28.27
