Answer: Choice A) -3
Work Shown:

Which leads us to choice A. In the second step, I used the rule that
is equivalent to
. For each equation, the b is the base. Note how logs undo exponents and vice versa.
I would think that thwe equation used to solve it would be 0.2 - r = s.
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
