A car has two wipers which do not overlap. Each wiper has a blade of length $25 c m$ sweeping through an angle of $115^{o}$ . Find the total area cleaned at each sweep of the blades.

Open in App

Solution

Area of Sector= $π r^{2} \times \frac{(θ)}{360 °}$
Here, $θ = 115 °$
$∴$ Area of swept= $π \times (25)^{2} \times \frac{115}{360} = 627.48 c m^{2}$
