Question

The minute hand of a circular clock is 15 cm long how far does the tip of the minute hand move in 1 hour.(π=3.14)

Answer 1

The minute hand travels a distance of the circumference of circle of radius 15 cm (length of the minute hand)

Therefore it travels the circumference.

Circumference =

$2\pi \times r \\ = 2 \times 3.14 \times 15 \\ = 30 \times 3.14 \\ = 94.2cm$

Thus, the minute hand travels a distance of 94.2cm

Answer 2

Answer:

Length of minute hand = 15 cm

∴ Radius = 15 cm

Circumference = 2πr

= 2 × 3.14 × 15 cm = 94.2 cm

Since the minute hand covers the distance in 1 hour equal to the circumference of the circle. Here the required distance covered by the minute hand = 94.2 cm.
