Common Mistakes to Avoid When Calculating the Square of 8649
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 else by swapping 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 using the formula.
The formula to find the square of the number is a². Instead, students may use 8649² with (8+6+4+9)² or (8000+600+40+9)². Students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing square and square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid this, 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 errors.
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 8649
Problem 1
Find the length of the square, where the area of the square is 74,764,401 cm².
The area of a square = a² So, the area of a square = 74,764,401 cm² So, the length = √74,764,401 = 8649. The length of each side = 8649 cm
Explanation
The length of a square is 8649 cm.
Because the area is 74,764,401 cm², the length is √74,764,401 = 8649.
Problem 2
Tom is planning to paint his square wall of length 8649 feet. The cost to paint a foot is 5 dollars. How much will it cost to paint the full wall?
The length of the wall = 8649 feet The cost to paint 1 square foot of wall = 5 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 = 8649 Therefore, the area of the wall = 8649² = 8649 × 8649 = 74,764,401. The cost to paint the wall = 74,764,401 × 5 = 373,822,005. The total cost = 373,822,005 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 373,822,005 dollars.
Problem 3
Find the area of a circle whose radius is 8649 meters.
The area of the circle = 235,619,718.78 m²
Explanation
The area of a circle = πr²
Here, r = 8649
Therefore, the area of the circle = π × 8649² = 3.14 × 8649 × 8649 = 235,619,718.78 m².
Problem 4
The area of the square is 74,764,401 cm². Find the perimeter of the square.
The perimeter of the square is 34,596 cm.
Explanation
The area of the square = a²
Here, the area is 74,764,401 cm²
The length of the side is √74,764,401 = 8649
Perimeter of the square = 4a
Here, a = 8649
Therefore, the perimeter = 4 × 8649 = 34,596.
Problem 5
Find the square of 8650.
The square of 8650 is 74,822,500.
Explanation
The square of 8650 is multiplying 8650 by 8650.
So, the square = 8650 × 8650 = 74,822,500.
