The time gap is 35 minutes.

In  60 minutes minute hand moves through 360 degrees.

In 35 minutes minute hand moves through 360/60 * 35 = 210.

The area swept = 210/360 * pi  * r * r

                           = 210/360 * 22/7 * 5 * 5

                           = 275/6

                          = 45.8.

 
Hope this helps!

Answer:

Angle swept by minute hand in 60 min = 360  

Angle swept by minute hand in 1 min = 360/60   =6

Angle swept by minute hand in 35 min  = 6 x 35 = 210

Area = 210/360 x 22/7 x 5x5 =45.83sq.cm
