Option A
The radius of circle is 19.90 cm
The formula for circumference of circle is given as:
[tex]C = 2 \pi r[/tex]
Where,
"C" is the circumference of circle
"r" is the radius of circle
[tex]\pi[/tex] is a constant equal to 3.14
Given that, circumference = 125 cm
To find: Radius of circle
Substitute the given value of "C" = 125 in formula
[tex]125 = 2 \times 3.14 \times r\\\\125 = 6.28 \times r\\\\r = \frac{125}{6.28}\\\\r = 19.90[/tex]
Thus radius of circle is 19.90 cm
