Question

A minute hand of a table clock is 3cm long how far does it tip move in 20 minute​

Answer 1

Answer:

9.4cm²

Step-by-step explanation:

3cm in a minute so find 20  

So, 20/60 x 360

= 120°     (Theta)

Area Covered = Area of sector with theta 120°

Therefore, Area of sector = theta /360 x pie r(radius) square or  360 x πr²

= 120/360 x 22/7 x 9

= 66/7

= 9.4 cm²
