Step 2: Multiply the number by itself using the multiplication button (×) That is 892 × 892
Step 3: Press the equal to button to find the answer Here, the square of 892 is 796,864.
Tips and Tricks for the Square of 892
Tips and tricks make it easy for students to understand and learn the square of a number. To master the square of a number, these tips and tricks will help students.
- The square of an even number is always an even number. For example, \(6^2 = 36\)
- The square of an odd number is always an odd number. For example, \(5^2 = 25\)
- The last digit of the square of a number is always 0, 1, 4, 5, 6, or 9.
- If the square root of a number is a fraction or a decimal, then the number is not a perfect square. For example, \(\sqrt{1.44} = 1.2\)
- The square root of a perfect square is always a whole number. For example, \(\sqrt{144} = 12\).
Common Mistakes to Avoid When Calculating the Square of 892
Mistakes are common among kids when doing math, especially when it is finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.
Mistake 1
Calculation errors:
Calculation errors mostly happen when students skip the steps or swap the digits. To avoid it, students should double-check the answer. They can double-check by finding the square root of the solution they found.
For example, the square of 25 is 625, and the square root of 625 is ±25.
Mistake 2
Errors will be using the formula.
The formula to find the square of the number is \(a^2\). Instead, students may use \(892^2\) with \(8+9+2)^2\) or \((800+92)^2\). So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing with square and square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid it, students should understand the concept that square and square root are inverse operations. The square of 5 is 25 and the square root of 25 is ±5.
Mistake 4
Errors in parentheses.
Ignoring the parentheses when finding the square of a number can lead to errors. So, students should understand parentheses. And do the operations in the correct order to avoid error.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number. So students should do regular practice to avoid errors.
Solved Examples on Square of 892
Problem 1
Find the length of the square, where the area of the square is 796,864 cm².
The area of a square = \(a^2\) So, the area of a square = 796,864 cm² So, the length = \(\sqrt{796,864} = 892\). The length of each side = 892 cm
Explanation
The length of a square is 892 cm.
Because the area is 796,864 cm², the length is \(\sqrt{796,864} = 892\).
Problem 2
An artist is planning to paint a square mural of length 892 feet. The cost to paint a foot is 5 dollars. Then how much will it cost to paint the full mural?
The length of the mural = 892 feet The cost to paint 1 square foot of the mural = 5 dollars. To find the total cost to paint, we find the area of the mural, Area of the mural = area of the square = \(a^2\) Here \(a = 892\) Therefore, the area of the mural = \(892^2 = 892 × 892 = 796,864\). The cost to paint the mural = 796,864 × 5 = 3,984,320. The total cost = 3,984,320 dollars
Explanation
To find the cost to paint the mural, we multiply the area of the mural by the cost to paint per foot.
So, the total cost is 3,984,320 dollars.
Problem 3
Find the area of a circle whose radius is 892 meters.
The area of the circle = 2,502,654.72 m²
Explanation
The area of a circle = \(\pi r^2\)
Here, \(r = 892\)
Therefore, the area of the circle = \(\pi × 892^2\) = \(3.14 × 892 × 892 = 2,502,654.72\) m².
Problem 4
The area of the square is 796,864 cm². Find the perimeter of the square.
The perimeter of the square is 3,568 cm.
Explanation
The area of the square = \(a^2\)
Here, the area is 796,864 cm²
The length of the side is \(\sqrt{796,864} = 892\)
Perimeter of the square = 4a
Here, \(a = 892\)
Therefore, the perimeter = 4 × 892 = 3,568 cm.
Problem 5
Find the square of 900.
The square of 900 is 810,000.
Explanation
The square of 900 is multiplying 900 by 900.
So, the square = 900 × 900 = 810,000.
