In a building there are 24 cylindrical pillars. The radius of each pillar is `28 cm` and height is `4 m.` Find the total cost of painting the curved surface area of all pillars at the rate of Rs 8 per `m^2.`

Text Solution

Verified by Experts

Given,
Height of each pillar = `4 m`
Radius of each pillar = `28 cm`
Now,
Curved surface area of pillar = `2pirh`
`=2xx22/7xx28/100xx4`
`=44xx16xx1/100`
`=704/100 m^2`
