Question

To the point the curved surface area aap cylindrical shaped pillar at the rate of 0.6 total 729 is spent. the area of the cylindrical base is 154m². find its height​

Answer 1

Answer:

area of base=154

πr2=154

r2=154*7/22 =49

r=7

now

total curved surface area =total ₹ spent/rate of per m2

2πrh=729/0.6=1215

h=1215*7/22*2*7

h=1215/44

h=27.61

height of cylider is 27.6
