Question

the minute needle of a clock whose length is 14 cm find the area by it in 5 minutes​

Answer 1

Answer:

51.33cm^2(approx)

in 5 minutes, it covers 5/60×360 degrees

ie, 30 degree

now, area of sector is theta/360×pi×r^2

ie, 1/12×22/7×14×14

ie,51.33cm^2(approx.)

Answer 2

Answer:

51.33 cm²

Step-by-step explanation:

Area covered by minute hand = ∅/360 * π * r² ( where Ф is the angle)

We know that, 360° = 60 mins

∴ 1 min = 6°

Angle covered in 5 minutes

6 x 5 = 30°

Area covered:

30/360 x 22/7 x 14 x 14

∴ Area covered = 51.33 cm²
