Answer 2

Step-by-step explanation:

Cylindrical pillars in a temple = 50

Radius of the pillar = 21cm

Height of the pillar = 4m

Total cost of painting at the rate of Rs6 per m = ?

●Now, convert the radius from cm to m

= 21/100=0.21

●Circumference of the cylindrical pillars = πr²

=22/7×0.21×0.21

=0.138

=0.14 (approx)

●CSA = circumference × height

=0.14 ×4

=0.56m²

●For 50 cylinders = 50 × CSA of the cylindrical pillars

=50×0.56

=28m²

●Total cost of painting at the rate of Rs6 per m = 28×6

=Rs168

hope it helps and pls mark me as brainliest

I did it by myself there is no such qns available on net given 50 cylinder so pls mark me as brainliest:)
