find the are of the first one and the circumference of the second one :)

Answer:
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
