Can you type the answers in plz. I can't see the pic
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
Any number to the power of 0 equals 1. Even if the original number is extremely high like 10000000, the value will still equal 1.
