Answer:
Circumference is 2piR =31.4
Area is pir^2=78.5
Step-by-step explanation:
To estimate this question, you can round the numbers to be compatible, to make it easier for yourself. The numbers should be able to be divided cleanly, as this is an estimate, not the actual problem solving. You could, for example, round 341 to 300, and 28 to 30, and divide them to get 10.
Hope that helped.
4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50
The answer is 16. 1^2 is 1, 2^2 is 4, 3^2 is 9, and 4^2 would be 16.
I cant get an exact area because pi is a never ending number but i got about 50.27 in
