The quadratic formula is -b plus minus the square root of b^2-4ac all over 2a.
Here, a=1, b=13, and c=30.
The only option that fills in the values correctly is D
= 1/2 (a + b) h let me know if this helps :)

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
