Question

the minute hand of a clock is 15cm long how far does the tip of the hand move during 35 minutes take pi as 3.14 plz ans fast its required urgently​

Answer 1

Answer:

94.29cm

Step-by-step explanation:

According to the sum,

The radius of the circular clock = Length of the minute hand (r) = 15 cm

Time taken = 1 hour.

The tip of the clock will undergo 1 complete rotation in 1 hour.

..The distance the minute hand moves in an hour = 2 x

= 2 × ² × 15

660 = 94.2857cm

94.29cm

Thus, the distance that the minute hand travels in one hour is 94.29 cm

Answer 2

Answer:

54.95 cm

Step-by-step explanation:

Let us take the radius of the clock as 15cm ( length of hand clock = radius of clock

perimeter of the clock =

$2\pi \times r$

$2 \times 3.14 \times 15$

$= 94.2$

Perimeter of circle = 60 minutes

So the minute hand should move 94.2 cm to cover 60 minutes

Then

Distance to cover one minute = 94.2 ÷ 60 = 1.57

Then Distance needed to cover 35 minutes =

1.57 × 35 = 54.95 cm

The distance needed to cover 35 minutes is 54.95
