Answer:
Step-by-step explanation:
Area of circle = π r²
r = 30
30² = 900
π = 3.14 or ≈ 3
A ≈ 900 × 3
A ≈ 2700
so C at 2830 is closest to the answer
so, what we do is, we multiply the value by a power of 10, that moves the recurring numbers to the left of the dot, in this case we want moved the "15", so we'll need two zeros, so we'll be using 100.
