The answer to number 1 is C. Not sure how to get that, I just got it off line converting it with a website.
The answer to number 2 in B, also got that offline by converting it.
3.) Area of a circle:
Radius-16
16×16×3.14=803.84 rounded to the nearest number is 804.
Since this says ESTIMATED we look for the closest answer to 804.
The answer is C. 805 square meters. hope it helps!!!!!!!!!!!!!!!
