Question

the length of the minute hand of a clock is 14cm find the area swept by the minute hand in 7:55 am to 8:05am

Answer 1

Answer:

Step-by-step explanation:

Total number of minutes in an hour =60

So each minute has a angle of 360/60=6 minutes

Time between 7:55am to 8:5am

= 10min

Angle of the minute hand = 10 *6 =60°

Radius(length of the minute hand) = 14cm

So area swept = 60/ 360x π x14²

= 102•67cm² or 308/3 cm²
