Answer:
Option D. 5890.5 feet²
Step-by-step explanation:
An individual head of a sprinkler system covers a circular are of grass with a radius of 25 feet.
Yard has three sprinkler heads that each cover circular area with no overlap.
We have to calculate the approximate area watered by these 3 sprinkler heads.
Area covered by one sprinkler = π×r² = π×(25)² = 625π feet²
Therefore area covered by three sprinkler heads = 3 × 625π = 5892.85 feet²
which matches the approximate value of Option D. 5890.5 feet²

One person throws away 4.5 x 10² g/day.
In 2013, there were 3.2 x 10⁶ people, so they threw away
(4.5 x 10² g/day)*(3.2 x 10⁶) = 1.44 x 10⁹ g/day.
Assume that there were 365 days in 2013.
The total trash thrown away was
(1.44 x 10⁹ g/day)*(365 days) = 5.26 x 10¹¹ g
Answer: 5.3 x 10¹¹ g
