Question

A clock has a diameter of 16 cm. How long is the metal band around it?

Answer 1

The length of metal band around the given clock is 50. 24 cm.

Explanation:

Here, the diameter of given clock = 16 cm

Now, Diameter = 2 x Radius

So, Radius = D/2 = 16 cm/2 = 8 cm

⇒The radius of the clock = 8 cm

Now, The metal Band around it = The CIRCUMFERENCE of the watch

Circumference of the clock = 2 π r

= 2 x ( 3.14) x ( 8) = 50.24 cm

or, C = 50.24 cm

Hence, the length of metal band around the given clock is 50. 24 cm.
