Answer:
B. A = pi • 8^2
Step-by-step explanation:
Area = pi • radius squared
radius is half of diameter so 16/2 = 8
You can use the commutative property to switch the order of the numbers. You could make it 20x5x9. 20x5=100 and 100x9=900.

Answer:
The total metric days are 458 days.
Step-by-step explanation:
1 metric year = 375 days
1 metric year = 10 metric months
1 metric month = 10 metric week
1 metric week = 10 metric days
4 metric months = 10 x 4 x 10 metric days = 400 metric days
5 metric weeks = 5 x 10 metric days = 50 metric days
So, the total number of metric days = 400 + 50 + 8 = 458 metric days
