For question 12 since the circumference is 24.5 inches than you need to divide that by to find the diameter and that would be 12.25 and then you divide 12.25 by 2 to find the radius and the radius is 6.1 then it will be 6.1 squared by 2 because the diameter = r times 2 so it will be 6.1 squared 2 than you multiply 6.1 times 2 and that equals 12.2 and then the area of circle would be 12.2π squared.
For question 13 it says the radius is 18ft so that would be 18 squared 2 and then you need to multiply 18 times 18 and this equals 324 so your area would be 324π ft squared by 2.
sry for not answering all of them i dont know how to do them yet but im learning about it but i hope can still get brainliest ty:)
