Answer:
A ≈ 254.5 in²
Option C
Step-by-step explanation:
Area of a Circle Formula: A = πr²
d = 2r
Since we are given diameter <em>d</em>, we simply divide by 2 to get radius <em>r</em>:
r = 18/2 = 9
Then we simply plug it into the formula:
A = π(9)²
A = 81π
A = 254.469
Answer:c if 18 is radius or d for the 18 is the radius
