Solved Examples on Square of 1111111
Problem 1
Find the length of the square, where the area of the square is 1,234,567,654,321 cm².
The area of a square = a² So, the area of a square = 1,234,567,654,321 cm² So, the length = √1,234,567,654,321 = 1,111,111. The length of each side = 1,111,111 cm
Explanation
The length of a square is 1,111,111 cm.
Because the area is 1,234,567,654,321 cm², the length is √1,234,567,654,321 = 1,111,111.
Problem 2
Sara is planning to tile her square floor with a side length of 1,111,111 feet. The cost to tile one square foot is 5 dollars. How much will it cost to tile the entire floor?
The length of the floor = 1,111,111 feet The cost to tile 1 square foot of floor = 5 dollars. To find the total cost to tile, we find the area of the floor. Area of the floor = area of the square = a² Here a = 1,111,111 Therefore, the area of the floor = 1,111,111² = 1,111,111 × 1,111,111 = 1,234,567,654,321. The cost to tile the floor = 1,234,567,654,321 × 5 = 6,172,838,271,605. The total cost = 6,172,838,271,605 dollars
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot.
So, the total cost is 6,172,838,271,605 dollars.
Problem 3
Find the area of a circle whose radius is 1,111,111 meters.
The area of the circle = 3,879,999,913,472.38 m²
Explanation
The area of a circle = πr²
Here, r = 1,111,111
Therefore, the area of the circle = π × 1,111,111² = 3.14 × 1,111,111 × 1,111,111 = 3,879,999,913,472.38 m².
Problem 4
The area of the square is 1,234,567,654,321 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 1,234,567,654,321 cm²
The length of the side is √1,234,567,654,321 = 1,111,111
Perimeter of the square = 4a
Here, a = 1,111,111
Therefore, the perimeter = 4 × 1,111,111 = 4,444,444.
