Answer:
The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.
Step-by-step explanation:
Given : In a building there are 30 cylindrical pillars. The radius of each pillar is 42 m and height is 7 m.
To find : The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter ?
Solution :
Radius of each pillar r= 42 m
Height of each pillar h= 7 m
The curved surface area of each pillar is
Substitute the value,
Area of 30 pillars is given by,
The curved surface area of all pillars at the rate of Rs.10 per square meter.
The cost painting is
Therefore, the total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.
