Solved Examples on Square of 904
Problem 1
Find the length of the square, where the area of the square is 817,216 cm².
The area of a square = a² So, the area of a square = 817,216 cm² So, the length = √817,216 = 904. The length of each side = 904 cm
Explanation
The length of a square is 904 cm.
Because the area is 817,216 cm², the length is √817,216 = 904.
Problem 2
Emma is planning to paint her square wall of length 904 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 904 feet The cost to paint 1 square foot of wall = 3 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a² Here a = 904 Therefore, the area of the wall = 904² = 904 × 904 = 817,216. The cost to paint the wall = 817,216 × 3 = 2,451,648. The total cost = 2,451,648 dollars
Explanation
To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot.
So, the total cost is 2,451,648 dollars.
Problem 3
Find the area of a circle whose radius is 904 meters.
The area of the circle = 2,570,154.56 m²
Explanation
The area of a circle = πr²
Here, r = 904
Therefore, the area of the circle = π × 904² = 3.14 × 904 × 904 = 2,570,154.56 m².
Problem 4
The area of the square is 817,216 cm². Find the perimeter of the square.
The perimeter of the square is 3,616 cm
Explanation
The area of the square = a²
Here, the area is 817,216 cm²
The length of the side is √817,216 = 904
Perimeter of the square = 4a
Here, a = 904
Therefore, the perimeter = 4 × 904 = 3,616 cm.
Problem 5
Find the square of 905.
The square of 905 is 819,025
Explanation
The square of 905 is multiplying 905 by 905.
So, the square = 905 × 905 = 819,025
