Question

cylindrical pillar is 50 centimetre in diameter and 3.5 metre in height these cost of printing East curved surface at the rate of rupees 12.50 metre square is_____​

Answer 1

Answer:

radius =half of dia=25

height= 3.5

total curved surface area=2πrh

half of the curved surface area(i.e. the east surface area)=πrh

=22*25*3.5/7

=275

that's why total cost to paint=275*122.50=₹6875

best of luck
