Step-by-step explanation:
in 60 minutes minutes hand make 360°
7:05-7:00= hours 0.05 minutes
in 5 minutes angle made by minutes hand
= (360°/60)(5)
= 30°
X= 30°
R= 14 cm
the area described by the minute hand on the face of clock between 7am to7.05 am = 30°× πr^2/360°
= 30°× 22 14×14/(7×360°)
= 51.333....sq cm
