    The formula for area is A=3.14r^2 In order to do this you will have to divide your diameter by two to get your radius r

    Yes your radius is 4 so now you can plug it into the formula. A=pir^2

    For the second part now since the frame is two inches thick all the way around so it adds four inches to your diameter but only two inches to your radius so you will do the exact same thing you did for part A but adding two to you radius so: A=pi(r+2)^2

    Yes it would be because 4+2=6 and 6^2 is 36! So your answer is 36pi good job!
