Solved Examples on Square of 40000
Problem 1
Find the length of the square, where the area of the square is 1,600,000,000 cm².
The area of a square = a² So, the area of a square = 1,600,000,000 cm² So, the length = √1,600,000,000 = 40000. The length of each side = 40000 cm
Explanation
The length of a square is 40000 cm.
Because the area is 1,600,000,000 cm² the length is √1,600,000,000 = 40000.
Problem 2
Sara is planning to cover her square garden of length 40000 feet with tiles. The cost of tiling per square foot is 5 dollars. How much will it cost to cover the full garden?
The length of the garden = 40000 feet The cost to tile 1 square foot of garden = 5 dollars. To find the total cost to cover, we find the area of the garden, Area of the garden = area of the square = a² Here a = 40000 Therefore, the area of the garden = 40000² = 40000 × 40000 = 1,600,000,000. The cost to cover the garden = 1,600,000,000 × 5 = 8,000,000,000. The total cost = 8,000,000,000 dollars
Explanation
To find the cost to cover the garden, we multiply the area of the garden by the cost to tile per foot.
So, the total cost is 8,000,000,000 dollars.
Problem 3
Find the area of a circle whose radius is 40000 meters.
The area of the circle = 5,024,000,000 m²
Explanation
The area of a circle = πr²
Here, r = 40000
Therefore, the area of the circle = π × 40000² = 3.14 × 40000 × 40000 = 5,024,000,000 m².
Problem 4
The area of the square is 1,600,000,000 cm². Find the perimeter of the square.
The perimeter of the square is 160,000 cm
Explanation
The area of the square = a²
Here, the area is 1,600,000,000 cm²
The length of the side is √1,600,000,000 = 40000
Perimeter of the square = 4a
Here, a = 40000
Therefore, the perimeter = 4 × 40000 = 160,000.
Problem 5
Find the square of 40100.
The square of 40100 is 1,608,010,000
Explanation
The square of 40100 is multiplying 40100 by 40100.
So, the square = 40100 × 40100 = 1,608,010,000
