Square of 4.4
The product of multiplying a number by itself is the square of a number. Square calculations are used in various fields like programming, calculating areas, and more. In this topic, we will discuss the square of 4.4.
What is the Square of 4.4
The square of a number is the product of the number with itself. The square of 4.4 is 4.4 × 4.4. In mathematics, this can be denoted as 4.4², where 4.4 is the base and 2 is the exponent. The square of a positive and a negative number is always positive. For example, 5² = 25; (-5)² = 25. The square of 4.4 is 4.4 × 4.4 = 19.36. Square of 4.4 in exponential form: 4.4² Square of 4.4 in arithmetic form: 4.4 × 4.4
How to Calculate the Value of Square of 4.4
The square of a number is calculated by multiplying the number by itself. Here are common methods used to find the square of a number. By Multiplication Method Using a Formula Using a Calculator
By the Multiplication method
In this method, we multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 4.4. Step 1: Identify the number. Here, the number is 4.4 Step 2: Multiplying the number by itself, we get, 4.4 × 4.4 = 19.36. The square of 4.4 is 19.36.
Using a Formula (a²)
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 4.4 So: 4.4² = 4.4 × 4.4 = 19.36
By Using a Calculator
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 4.4. Step 1: Enter the number in the calculator Enter 4.4 in the calculator. Step 2: Multiply the number by itself using the multiplication button (×) That is 4.4 × 4.4 Step 3: Press the equal button to find the answer Here, the square of 4.4 is 19.36. Tips and Tricks for the Square of 4.4 Tips and tricks can make it easier 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 integer is always an even number. For example, 6² = 36 - The square of an odd integer is always an odd number. For example, 5² = 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, √1.44 = 1.2 - The square root of a perfect square is always a whole number. For example, √144 = 12.
Common Mistakes to Avoid When Calculating the Square of 4.4
Mistakes are common among learners when doing math, especially when 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 steps or swap digits. To avoid this, students should double-check their answers. They can double-check by finding the square root of the solution they found. For example, the square of 2.5 is 6.25, and the square root of 6.25 is ±2.5.
Solved Examples on Square of 4.4
Problem 1
A square-shaped garden has an area of 19.36 m². Find the length of one side of the garden.
The area of a square = a² So, the area of the square = 19.36 m² So, the length = √19.36 = 4.4. The length of each side = 4.4 m
Explanation
The length of each side of the square-shaped garden is 4.4 m. Because the area is 19.36 m², the length is √19.36 = 4.4.
Problem 2
Sarah is planning to tile her square floor of length 4.4 meters. The cost to tile a square meter is 20 dollars. How much will it cost to tile the entire floor?
The length of the floor = 4.4 meters The cost to tile 1 square meter of the floor = 20 dollars. To find the total cost to tile, we find the area of the floor, Area of the floor = area of the square = a² Here a = 4.4 Therefore, the area of the floor = 4.4² = 4.4 × 4.4 = 19.36. The cost to tile the floor = 19.36 × 20 = 387.2. The total cost = 387.2 dollars
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per square meter. So, the total cost is 387.2 dollars.
Problem 3
Find the area of a circle whose radius is 4.4 meters.
The area of the circle = 60.82 m²
Explanation
The area of a circle = πr² Here, r = 4.4 Therefore, the area of the circle = π × 4.4² = 3.14 × 4.4 × 4.4 = 60.82 m².
Problem 4
A square's area is 19.36 cm². Find the perimeter of the square.
The perimeter of the square is 17.6 cm
Explanation
The area of the square = a² Here, the area is 19.36 cm² The length of the side is √19.36 = 4.4 Perimeter of the square = 4a Here, a = 4.4 Therefore, the perimeter = 4 × 4.4 = 17.6 cm.
Problem 5
Find the square of 5.5.
The square of 5.5 is 30.25
Explanation
The square of 5.5 is found by multiplying 5.5 by 5.5. So, the square = 5.5 × 5.5 = 30.25
