Given : A door is fixed at the point o
Opened by on angle of 30°.
the area swept by the door was 25/12π m sq.
To Find : the width of the door
Solution :
Width of Door = Radius = R m
Area of Sector = ( Angle / 360°) * πR²
Angle = 30°.
Area of Sector = (30° / 360°) * πR²
= (1/12) πR² m²
area swept by the door was 25/12π m²
(1/12) πR² = 25/12π
=> R² = 25/π ²
=> R = 5/π
width of the door = 5/π m
