- 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 9000.
Step 1: Identify the number. Here, the number is 9000
Step 2: Multiplying the number by itself, we get, 9000 × 9000 = 81,000,000.
The square of 9000 is 81,000,000.
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 9000
So: 9000² = 9000 × 9000 = 81,000,000
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 9000.
Step 1: Enter the number in the calculator Enter 9000 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 9000 × 9000
Step 3: Press the equal to button to find the answer
Here, the square of 9000 is 81,000,000.
Tips and Tricks for the Square of 9000
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 9000
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 will be using the formula.
The formula to find the square of the number is a². Instead, students may use 9000² with (900 +0)² or (9000 + 0)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing with square and square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid it, 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 error.
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 9000
Problem 1
Find the cost to tile a square floor where the area is 81,000,000 square inches and the cost per square inch is 0.5 dollars.
The area of the floor = 9000² square inches The cost to tile 1 square inch = 0.5 dollars Total cost to tile the floor = 81,000,000 × 0.5 = 40,500,000 dollars
Explanation
To find the cost to tile the floor, multiply the area by the cost per square inch.
So, the total cost is 40,500,000 dollars.
Problem 2
A square garden has a side length of 9000 cm. If a fence costs 2 dollars per cm, what is the total cost to fence the garden?
The side length of the garden = 9000 cm Perimeter of the garden = 4 × 9000 = 36,000 cm Cost to fence 1 cm = 2 dollars Total cost = 36,000 × 2 = 72,000 dollars
Explanation
To find the total cost to fence the garden, multiply the perimeter by the cost per cm.
So, the total cost is 72,000 dollars.
Problem 3
Calculate the area of a circle with a radius of 9000 meters.
The area of the circle = 254,469,000 m²
Explanation
The area of a circle = πr²
Here, r = 9000
Therefore, the area of the circle = π × 9000² = 3.14 × 9000 × 9000 = 254,469,000 m².
Problem 4
If the area of a square field is 81,000,000 square feet, what is the length of each side of the field?
The side length of the field is 9000 feet.
Explanation
The area of the square = a²
Here, the area is 81,000,000 square feet
The length of the side is √81,000,000 = 9000
Problem 5
Find the square of 9001.
The square of 9001 is 81,018,001
Explanation
The square of 9001 is multiplying 9001 by 9001.
So, the square = 9001 × 9001 = 81,018,001
