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
