A car has two wipers which do not overlap. Each wiper has a blade of length `25` cm sweeping through an angle of `115^@` . Find the total area cleaned at each sweep of the blades.

Text Solution

Verified by Experts

The correct Answer is:
`1254.46` sq. cm

Each wiper clears a sector of angle `115^@` and radius `25` cm
Area of each sector `=(115/360)pi(25)^2`
`=627.23` sq. cm.
Therefore, the total area cleared at each sweep of the blades
`=2xx627.23=1254.46` sq. cm
