Square of 165
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 this topic, we will discuss the square of 165.
What is the Square of 165
The square of a number is the product of the number itself. The square of 165 is 165 × 165. The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 165², where 165 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 165 is 165 × 165 = 27225. Square of 165 in exponential form: 165² Square of 165 in arithmetic form: 165 × 165
How to Calculate the Value of Square of 165
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 165.
Step 1: Identify the number. Here, the number is 165.
Step 2: Multiplying the number by itself, we get, 165 × 165 = 27225. The square of 165 is 27225.
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 165. So: 165² = 165 × 165 = 27225
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 165.
Step 1: Enter the number in the calculator Enter 165 in the calculator.
Step 2: Multiply the number by itself using the multiplication button(×) That is 165 × 165
Step 3: Press the equal to button to find the answer Here, the square of 165 is 27225.
Tips and Tricks for the Square of 165 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, 6² = 36 The square of an odd number 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 165
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.
Solved Examples on Square of 165
Problem 1
Find the length of the square, where the area of the square is 27225 cm².
The area of a square = a² So, the area of a square = 27225 cm² So, the length = √27225 = 165. The length of each side = 165 cm
Explanation
The length of a square is 165 cm.
Because the area is 27225 cm², the length is √27225 = 165.
Problem 2
Sarah is planning to tile her square patio of length 165 feet. The cost to tile a foot is 4 dollars. Then how much will it cost to tile the full patio?
The length of the patio = 165 feet The cost to tile 1 square foot of the patio = 4 dollars. To find the total cost to tile, we find the area of the patio, Area of the patio = area of the square = a² Here a = 165 Therefore, the area of the patio = 165² = 165 × 165 = 27225. The cost to tile the patio = 27225 × 4 = 108900. The total cost = 108900 dollars
Explanation
To find the cost to tile the patio, we multiply the area of the patio by the cost to tile per foot.
So, the total cost is 108900 dollars.
Problem 3
Find the area of a circle whose radius is 165 meters.
The area of the circle = 85516.5 m²
Explanation
The area of a circle = πr²
Here, r = 165
Therefore, the area of the circle = π × 165²
= 3.14 × 165 × 165
= 85516.5 m².
Problem 4
The area of the square is 27225 cm². Find the perimeter of the square.
The perimeter of the square is 660 cm.
Explanation
The area of the square = a²
Here, the area is 27225 cm²
The length of the side is √27225 = 165
Perimeter of the square = 4a
Here, a = 165
Therefore, the perimeter = 4 × 165 = 660 cm.
Problem 5
Find the square of 166.
The square of 166 is 27556.
Explanation
The square of 166 is multiplying 166 by 166.
So, the square = 166 × 166 = 27556.
