Square of 3.14
The product of multiplying a number by itself is the square of that number. Squares are used in programming, calculating areas, and more. In this topic, we will discuss the square of 3.14.
What is the Square of 3.14
The square of a number is the product of the number itself. The square of 3.14 is 3.14 × 3.14. We write it in math as \(3.14^2\), where 3.14 is the base and 2 is the exponent. The square of a positive and a negative number is always positive. For example, \(5^2 = 25\); \((-5)^2 = 25\). The square of 3.14 is 3.14 × 3.14 = 9.8596. Square of 3.14 in exponential form: \(3.14^2\) Square of 3.14 in arithmetic form: 3.14 × 3.14
How to Calculate the Value of Square of 3.14
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. By Multiplication Method Using a Formula Using a Calculator
By the Multiplication Method
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 3.14 Step 1: Identify the number. Here, the number is 3.14 Step 2: Multiplying the number by itself, we get, 3.14 × 3.14 = 9.8596. The square of 3.14 is 9.8596.
Using a Formula (\(a^2\))
In this method, the formula, \(a^2\) is used to find the square of the number. Where \(a\) is the number. Step 1: Understanding the equation Square of a number = \(a^2\) \(a^2 = a × a\) Step 2: Identifying the number and substituting the value in the equation. Here, ‘a’ is 3.14 So: \(3.14^2 = 3.14 × 3.14 = 9.8596\)
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 3.14. Step 1: Enter the number in the calculator Enter 3.14 in the calculator. Step 2: Multiply the number by itself using the multiplication button (×) That is 3.14 × 3.14 Step 3: Press the equal to button to find the answer Here, the square of 3.14 is 9.8596. Tips and Tricks for the Square of 3.14 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 square of a decimal number may not always be a whole number. For example, \(1.5^2 = 2.25\) 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 3.14
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 2.5 is 6.25, and the square root of 6.25 is ±2.5.
Solved Examples on Square of 3.14
Problem 1
Find the area of a circular garden where the radius is 3.14 meters.
The area of the circle = 30.974 m²
Explanation
The area of a circle = \(\pi r^2\) Here, \(r = 3.14\) Therefore, the area of the circle = \(\pi × 3.14^2\) = \(3.14 × 3.14 × 3.14 = 30.974\) m².
Problem 2
A square table has a side length of 3.14 meters. What is the area of the table?
The area of the square table is 9.8596 m².
Explanation
The area of a square = \(a^2\) Here, \(a = 3.14\) Therefore, the area = \(3.14 × 3.14 = 9.8596\) m².
Problem 3
A rectangular plot has a width of 3.14 meters and a length of 3.14 meters. What is the perimeter of the plot?
The perimeter of the plot is 12.56 meters.
Explanation
The perimeter of a rectangle = 2 × (length + width) Here, length = 3.14, width = 3.14 Therefore, the perimeter = 2 × (3.14 + 3.14) = 12.56 meters.
Problem 4
A circular track has a radius of 3.14 meters. What is the circumference of the track?
The circumference of the track is 19.736 meters.
Explanation
The circumference of a circle = \(2\pi r\) Here, \(r = 3.14\) Therefore, the circumference = \(2 × 3.14 × 3.14 = 19.736\) meters.
Problem 5
Find the square of 3.15.
The square of 3.15 is 9.9225.
Explanation
The square of 3.15 is multiplying 3.15 by 3.15. So, the square = 3.15 × 3.15 = 9.9225.
