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.
Answer:
704 cm²
Step-by-step explanation:
The circumference of the cylindrical container is given by 2πr.
Now, r = radius of the base
If the diameter of the base is 14 cm then the radius will be 7 cm.
So, the circumference = cm.
Now, the label around the surface of the container placed 2 cm from top and bottom.
Therefore, the width of the label is (20 - 2 - 2) = 16 cm and the length is 44 cm.
Hence, the area of each label is (44 × 16) = 704 cm² (Answer)
Answer:
54 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is
A = ( s is the side length ) then
= 81
( multiply both sides by 4 to clear the fraction )
s² = 324
( divide both sides by
)
s² = 324 ( take the square root of both sides )
s = = 18
Thus
perimeter = 3 × 18 = 54 cm
