1. A circular wheel make 420 rounds per minute with a speed of 55.44 km/hr. Find the radius of the
wheel.
2. Find the radius of a circle, if an arc of angle 1200 has length of 24 cm. Also, find the area of the
sector formed by this arc.
3. A wire is bent in the form of a circle of area 3850 sq cm. If the same wire is bent in the form of a
rectangle of length 65cm, find the area of the rectangle formed.
4. A chord of a circle subtends an angle of 1200 at the centre. Find the area of the corresponding
segment of the circle whose radius is 12cm. ( use p = 3.14, Ö3 = 1.73 )
5. The minute hand of a clock is 10cm long. Find the area on the face of the clock described by the
minute hand between 9a.m and 9.35a.m.
6. A car has two wipers which do not overlap. Each wiper has a blade of length 25cm sweeping
through an angle of 1150. Find the total area cleaned at each sweep of the blades.
