Find the length of a square, where the area of the square is 12345678987654321 cm².
The area of a square = a² So, the area of a square = 12345678987654321 cm² So, the length = √12345678987654321 = 111111111. The length of each side = 111111111 cm.
The length of a square is 111111111 cm.
Because the area is 12345678987654321 cm² the length is √12345678987654321 = 111111111.
Anna is planning to tile her square patio of length 111111111 inches. The cost to tile a square inch is 2 dollars. Then how much will it cost to tile the full patio?
The length of the patio = 111111111 inches The cost to tile 1 square inch of the patio = 2 dollars. To find the total cost to tile, we find the area of the patio, Area of the patio = area of the square = a² Here a = 111111111 Therefore, the area of the patio = 111111111² = 111111111 × 111111111 = 12345678987654321. The cost to tile the patio = 12345678987654321 × 2 = 24691357975308642. The total cost = 24691357975308642 dollars.
To find the cost to tile the patio, we multiply the area of the patio by the cost to tile per square inch.
So, the total cost is 24691357975308642 dollars.
Find the area of a circle whose radius is 111111111 meters.
The area of the circle = 387850641722322.8 m²
The area of a circle = πr²
Here, r = 111111111
Therefore, the area of the circle = π × 111111111² = 3.14 × 111111111 × 111111111 = 387850641722322.8 m².
The area of a square is 12345678987654321 cm². Find the perimeter of the square.
The perimeter of the square is 444444444 cm.
The area of the square = a²
Here, the area is 12345678987654321 cm²
The length of the side is √12345678987654321 = 111111111
Perimeter of the square = 4a
Here, a = 111111111
Therefore, the perimeter = 4 × 111111111 = 444444444 cm.
