Answer:
Option A is correct.
Circumference of a circle = 32.03 cm
Step-by-step explanation:
Circumference of a circle(C) is given by:
.....[1]
where,
r is the radius of the circle.
As per the statement:
Use pi = 3.14.
Radius of the circle(r) = 5.1 cm
Substitute these given values in [1] to find C;
Simplify:
C = 32.028 cm
Therefore, the approximate value of the circumference of a circle is, 32.03 cm
