Question

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

Answer 1

Area of Sector=$\pi r^2\times \frac{\left(\theta \right)}{360°}$

Here, $\theta =115°$

$\therefore$ Area of swept=$\pi \times (25{)}^2\times \frac{115}{360}=627.48c{m}^2$
