Question

the length of the minute hand 5cm raju said the area swept by the minute hand during the time period 6.05 am and 6.40 am is 45 5/6 cm² do you agree with raju? give reasons​

Answer 1

Answer:helloStep-by-step explanation:i think this is the answer

first of all,

time taken 35 minutes

area swept in 60 minutes

by minutes hand =360

in 35 minutes =360/60×35

so 210

area 210/360×22/7×5×5

=11×25/6275/

6 cm^2

HOPE IT HELPS YOU

Answer 2

Raju is correct.

Step-by-step explanation:

Consider the provided information.

60 minutes = 360°

1 minute = 6°

The time difference is 6:40-6:05=35 minutes.

So, the value of θ is= 35×6°=210°

To find the area of sector use the formula: $A=\frac{\theta}{360}\pi r^2$

$A=\frac{210}{360}\times\frac{22}{7} \times5\times5$

$A=\frac{11}{6} \times5\times5\\\\A=\frac{275}{6}\\\\A=45\frac{5}{6}$

The area swept by the minute hand is $45\frac{5}{6}$ cm².

Hence, Raju is correct.
