Answer:
The circumference of clock is, 53.38 cm
Step-by-step explanation:
Circumference(C) of the circle is given by:
\(C = 2 \pi r\) ....[1]
where, r is the radius of the circle.
As per the statement:
the radius of a clock face is 8.5 centimeters
⇒r = 8.5 cm
Use\(\pi = 3.14\)
Substitute the given values in [1] we have;
\(C = 2 \cdot 3.14 \cdot 8.5\)
Simplify:
C = 53.38 cm
Therefore, the circumference of clock is, 53.38 cm
