**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.**

Answer:

Given,

Radius (r) = 25 cm

Sector angle (θ) = 115°

Since there are 2 blades,

The total area of the sector made by wiper

= 2×(\frac{θ}{360°})×π r^2\\ = 2×(\frac{115}{360})×(\frac{22}{7})×(25)^2\\ = 2×\frac{158125}{252}\ cm^2\\ = \frac{158125}{126} = 1254.96\ cm^2\\
