The product of multiplying an integer by itself is the square of a number. Square is used in programming, calculating areas, and so on. In the topic, we will discuss the square of 489.
The square of a number is the product of the number itself.
The square of 489 is 489 × 489.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 489², where 489 is the base and 2 is the exponent.
The square of a positive and a negative number is always positive. For example, 5² = 25; -5² = 25.
The square of 489 is 489 × 489 = 239,121.
Square of 489 in exponential form: 489²
Square of 489 in arithmetic form: 489 × 489
The square of a number is multiplying the number by itself. So let’s learn how to find the square of a number. These are the common methods used to find the square of a number.
In this method, we will multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 489.
Step 1: Identify the number. Here, the number is 489.
Step 2: Multiplying the number by itself, we get, 489 × 489 = 239,121.
The square of 489 is 239,121.
In this method, the formula, a² is used to find the square of the number. Where a is the number.
Step 1: Understanding the equation Square of a number = a²
a² = a × a
Step 2: Identifying the number and substituting the value in the equation.
Here, ‘a’ is 489
So: 489² = 489 × 489 = 239,121
Using a calculator to find the square of a number is the easiest method. Let’s learn how to use a calculator to find the square of 489.
Step 1: Enter the number in the calculator. Enter 489 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 489 × 489
Step 3: Press the equal to button to find the answer. Here, the square of 489 is 239,121.
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.
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.
Find the length of the square, where the area of the square is 239,121 cm².
The area of a square = a²
So, the area of a square = 239,121 cm²
So, the length = √239,121 = 489.
The length of each side = 489 cm
The length of a square is 489 cm. Because the area is 239,121 cm² the length is √239,121 = 489.
Sarah is planning to wallpaper her square wall of length 489 feet. The cost to wallpaper a foot is 3 dollars. Then how much will it cost to wallpaper the full wall?
The length of the wall = 489 feet The cost to wallpaper 1 square foot of wall = is 3 dollars. To find the total cost to wallpaper, we find the area of the wall, Area of the wall = area of the square = a² Here a = 489 Therefore, the area of the wall = 489² = 489 × 489 = 239,121. The cost to wallpaper the wall = 239,121 × 3 = 717,363. The total cost = 717,363 dollars
To find the cost to wallpaper the wall, we multiply the area of the wall by the cost to wallpaper per foot. So, the total cost is 717,363 dollars.
Find the area of a circle whose radius is 489 meters.
The area of the circle = 750,778.02 m²
The area of a circle = πr²
Here, r = 489
Therefore, the area of the circle = π × 489² = 3.14 × 489 × 489 = 750,778.02 m².
The area of the square is 239,121 cm². Find the perimeter of the square.
The perimeter of the square is
The area of the square = a²
Here, the area is 239,121 cm²
The length of the side is √239,121 = 489
Perimeter of the square = 4a Here, a = 489
Therefore, the perimeter = 4 × 489 = 1,956.
Find the square of 490.
The square of 490 is 240,100
The square of 490 is multiplying 490 by 490.
So, the square = 490 × 490 = 240,100
