Answer:

The circumference of clock is, 53.38 cm

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
