Answer:

  • area = π/16 in²
  • circumference = (3/4)π in

Step-by-step explanation:

The area formula is ...

  A = πr²

When r = 1/4 in, the area is ...

  A = π(1/4 in)² = π/16 in²

__

The circumference formula is ...

  C = πd

When the diameter is 3/4 in, the circumference is ...

  C = π(3/4 in) = (3/4)π in
