Answer:

a=95.0 in^2

Step-by-step explanation:

The area of a circle is:

a=\pir^2

First, we must find the radius

r=d/2

r=11/2

r=5.5

Substitute 5.5 in for r in the formula

a=\pi5.5^2

a=\pi30.25

Substitute 3.14 in for pi  

a=3.14*30.25

a=94.985

Rounded to the nearest tenth:

a=95.0 in^2

Hope this helps! :)

The pattern is that it +6 every number.

-5 + 6 = 1
