Answer:
12.56cm
Step-by-step explanation:
Step 1.
Find Radius of Circle P
Radius = [tex]\sqrt{\frac{a}{\pi} }[/tex]
=[tex]\sqrt{\frac{50.24}{3.14} }[/tex]
=4
Step 2.
Decrease by Radius by 50%
4×[tex]\frac{1}{2}[/tex]
=2
Step 3.
Find the new circumference using the new radius
C=πr²
=π×2²
=12.56
∴ The new circumference of Circle P is 12.56cm
