Solved Examples on Square of 4891
Problem 1
Find the length of the square, where the area of the square is 23,911,081 cm².
The area of a square = a² So, the area of a square = 23,911,081 cm² So, the length = √23,911,081 = 4891. The length of each side = 4891 cm
Explanation
The length of a square is 4891 cm.
Because the area is 23,911,081 cm², the length is √23,911,081 = 4891.
Problem 2
Sara is planning to tile her square courtyard of length 4891 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full courtyard?
The length of the courtyard = 4891 feet The cost to tile 1 square foot of courtyard = 5 dollars. To find the total cost to tile, we find the area of the courtyard, Area of the courtyard = area of the square = a² Here a = 4891 Therefore, the area of the courtyard = 4891² = 4891 × 4891 = 23,911,081. The cost to tile the courtyard = 23,911,081 × 5 = 119,555,405. The total cost = 119,555,405 dollars
Explanation
To find the cost to tile the courtyard, we multiply the area of the courtyard by the cost to tile per foot.
So, the total cost is 119,555,405 dollars.
Problem 3
Find the area of a circle whose radius is 4891 meters.
The area of the circle = 75,192,691.54 m²
Explanation
The area of a circle = πr²
Here, r = 4891
Therefore, the area of the circle = π × 4891² = 3.14 × 4891 × 4891 = 75,192,691.54 m².
Problem 4
The area of the square is 23,911,081 cm². Find the perimeter of the square.
The perimeter of the square is 19,564 cm.
Explanation
The area of the square = a²
Here, the area is 23,911,081 cm²
The length of the side is √23,911,081 = 4891
Perimeter of the square = 4a
Here, a = 4891
Therefore, the perimeter = 4 × 4891 = 19,564 cm.
Problem 5
Find the square of 4900.
The square of 4900 is 24,010,000
Explanation
The square of 4900 is multiplying 4900 by 4900.
So, the square = 4900 × 4900 = 24,010,000
