I think you are supposed to find the perimeter of it so you add all sides together to get your answer
Answer:
1,256 dm^2 and 400π dm^2
Step-by-step explanation:
The circumference is equal to 2pi times the radius. So 40pi=2pi times the radius so the radius is 20. The area of a circle is pi times the radius squared or 400pi and if using 3.14 for pi this would be 1,256 dm^2
The ratio from 80 to 5 would be 16. so divide 144 by 16 and you get 9. Answer:9
The answer is “12p+10”
4p+8p+10
12p+10
