Solved Examples on Square of 390625
Problem 1
Find the length of the side of a square, where the area of the square is 152587890625 cm².
The area of a square = a² So, the area of a square = 152587890625 cm² So, the length = √152587890625 = 390625. The length of each side = 390625 cm
Explanation
The length of a square is 390625 cm because the area is 152587890625 cm²; the length is √152587890625 = 390625.
Problem 2
Anna is planning to carpet her square room with a length of 390625 meters. The cost to carpet per square meter is 5 dollars. How much will it cost to carpet the full room?
The length of the room = 390625 meters The cost to carpet 1 square meter of the room = 5 dollars. To find the total cost to carpet, we find the area of the room. Area of the room = area of the square = a² Here a = 390625. Therefore, the area of the room = 390625² = 152587890625. The cost to carpet the room = 152587890625 × 5 = 762939453125. The total cost = 762939453125 dollars
Explanation
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per square meter.
So, the total cost is 762939453125 dollars.
Problem 3
Find the area of a circle whose radius is 390625 meters.
The area of the circle = 478828318401.78 m²
Explanation
The area of a circle = πr²
Here, r = 390625.
Therefore, the area of the circle = π × 390625² = 3.14 × 390625 × 390625 = 478828318401.78 m².
Problem 4
The area of a square is 152587890625 cm². Find the perimeter of the square.
The perimeter of the square is 1562500 cm.
Explanation
The area of the square = a²
Here, the area is 152587890625 cm².
The length of the side is √152587890625 = 390625.
Perimeter of the square = 4a
Here, a = 390625.
Therefore, the perimeter = 4 × 390625 = 1562500 cm.
Problem 5
