Fourteen circular pillars of a building are to be painted. If the diameter of each pillar is 50 cm and height 4 m, find the total area to be painted. Also find the total cost of paint at the rate of Rs. 6.5 per sq. m
Answers
Answer:
Given :
Given :d=50 m
Given :d=50 mh=4 m
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25)
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25) 2
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25) 2 ×4×10=15.7m
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25) 2 ×4×10=15.7m 2
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25) 2 ×4×10=15.7m 2 [r=
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25) 2 ×4×10=15.7m 2 [r= 2
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25) 2 ×4×10=15.7m 2 [r= 250cm
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25) 2 ×4×10=15.7m 2 [r= 250cm
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25) 2 ×4×10=15.7m 2 [r= 250cm =25cm=0.25m]
Given :d=50 mh=4 mSurface area of 10 cylindrical pillars =2πrh×10=2×3.14(0.25) 2 ×4×10=15.7m 2 [r= 250cm =25cm=0.25m]Cost of painting =Rs.(15.7×0.50)=Rs.7.85
