Answer:
Answer:
Total cuÅved surface area of the pillars =Ā 985.6mĀ²Total cost of painting =Ā Rs.5420.8
Explanation:
Given,
A cylindrical pillar with dimĆØnsions,
r(radius) = 56/2 = 28cm. [ Since d = r/2]h(height) = 35m
There are 16 such pillars. Find the cost of paiƱting the the curved surface area of all pillars 5.50/mĀ²
ConversionĀ ofĀ theĀ dimensioƱsĀ inĀ sameĀ units.
Radius = 28cm
= 28 Ć· 100 [Since 1m = 100]
= 0.28m
CuÅved surface area of the pillar is given by,
ā 2Ļrh
Where,
TakingĀ āĻāĀ as 22/7
ā 2*(22/7)*(0.28)*(35)
