Please help me out with this

Answer:
[tex]\frac{9}{64}[/tex] π in²
Step-by-step explanation:
The area (A) of the circle is calculated using the formula
A = πr² ← r is the radius
here the diameter = [tex]\frac{3}{4}[/tex]
and radius is half the diameter, hence
r = [tex]\frac{3}{8}[/tex], so
A = π × ([tex]\frac{3}{8}[/tex] )² = [tex]\frac{9}{64}[/tex] π in²
