Answer:
18.2+8.5=26.7
Step-by-step explanation:
Since the area formula is pi times radius to the second power, then just plug in the things you know. for ex: The area is 314, then work backwards and divide 314 by pi which equals 100 then unsquare it which is 10 because 10*10=100. So the radius is 10
This is false because a prime factorization can only contain prime numbers.
