Answer: 25.12 milimeters
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the button's radius:
Area of a circle= π radius^2
Replacing with the values given:
50.24 = 3.14 r^2
50.24 / 3.14 = r^2
16 = r^2
√16 =r
r= 4 mm
Now, to find the circumference
Circumference = 2πr
Replacing:
C = 2 (3.14) 4 = 25.12 milimeters
