Determine the area of the unshaded region​

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
