Answer:

Circumference

The circumference of a circle can be found using:

c=2πr

We know the radius is 18, so we can substitute 18 in for r

c=2π18

Multiply

c=36π

c=113.097335529

To the nearest hundreth:

c=113.10 inches

Area

The area of a circle can be found using:

a=πr^2

We know the radius is 18, so we can substitute 18 in for r

a=π18^2

a=π324

a=1017.87601976

To the nearest hundreth

a=1017.88 inches^2
