Solved Examples on Square of 66666667
Problem 1
Find the length of a square, where the area of the square is 4444444488888889 cm².
The area of a square = a² So, the area of a square = 4444444488888889 cm² So, the length = √4444444488888889 = 66666667. The length of each side = 66666667 cm
Explanation
The length of a square is 66666667 cm.
Because the area is 4444444488888889 cm², the length is √4444444488888889 = 66666667.
Problem 2
Sarah is planning to tile her square floor of length 66666667 feet. The cost to tile a foot is 3 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 66666667 feet The cost to tile 1 square foot of floor = 3 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 = 66666667 Therefore, the area of the floor = 66666667² = 66666667 × 66666667 = 4444444488888889. The cost to tile the floor = 4444444488888889 × 3 = 13333333466666667. The total cost = 13333333466666667 dollars
Explanation
To find the cost to tile the floor, multiply the area of the floor by the cost to tile per foot.
So, the total cost is 13333333466666667 dollars.
Problem 3
Find the area of a circle whose radius is 66666667 meters.
The area of the circle = 139537206678.66 m²
Explanation
The area of a circle = πr²
Here, r = 66666667
Therefore, the area of the circle = π × 66666667² = 3.14 × 66666667 × 66666667 = 139537206678.66 m².
Problem 4
The area of a square is 1396 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 1396 cm²
The length of the side is √1396 ≈ 37.36
Perimeter of the square = 4a
Here, a ≈ 37.36
Therefore, the perimeter ≈ 4 × 37.36 = 149.44.
Problem 5
Find the square of 38.
The square of 38 is 1444
Explanation
The square of 38 is multiplying 38 by 38.
So, the square = 38 × 38 = 1444
