Answer:
154 cm^2
Step-by-step explanation:
Minute hand completes full circle degree in 60 minutes.
Angle swept by minute in 60 minutes =360°
Angle swept by the minute hand in 15minutes =60360°×15=90°
Therefore,
θ=90°
Length of minute hand =r=14cm
Area swept by minute hand in 15 minutes =Area of sector
As we know that area of sector is given as-
A=360°θ×πr2
Therefor,
Area swept by the minute hand in 15minutes =360°90°×(722×(14)2)=41×616=154cm2
Hence the area swept by the minute hand in 15 minutes is 154cm2.
Hence the correct answer is 154cm2.
