Answer 2

Answer:

plz mark me as brainliest

Step-by-step explanation:

pillar=16 cm

radius of cylindrical pullers = 1/2 *diameter

=1/2*98

=49cm

height of cylindrical pillars = 7m

=700cm

lateral surface of area 16 cylindrical pillars= 2 pie rh

2*22/7 *49/100* 7cm^2

surface of area 16 cylindrical pillars = 34496cm^2

Hence, total cost of painting at the rate of Rs 22 per m ^2= 758912
