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 394.
The square of a number is the product of the number itself.
The square of 394 is 394 × 394.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 394², where 394 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 394 is 394 × 394 = 155,236.
Square of 394 in exponential form: 394²
Square of 394 in arithmetic form: 394 × 394
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 394.
Step 1: Identify the number. Here, the number is 394.
Step 2: Multiplying the number by itself, we get, 394 × 394 = 155,236.
The square of 394 is 155,236.
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 394.
So: 394² = 394 × 394 = 155,236
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 394.
Step 1: Enter the number in the calculator Enter 394 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 394 × 394
Step 3: Press the equal to button to find the answer
Here, the square of 394 is 155,236.
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 students 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 155,236 cm².
The area of a square = a² So, the area of a square = 155,236 cm² So, the length = √155,236 = 394. The length of each side = 394 cm
The length of a square is 394 cm.
Because the area is 155,236 cm², the length is √155,236 = 394.
Sarah is planning to tile her square garden of length 394 feet. The cost to tile a square foot is 5 dollars. Then how much will it cost to tile the full garden?
The length of the garden = 394 feet The cost to tile 1 square foot of the garden = 5 dollars. To find the total cost to tile, we find the area of the garden, Area of the garden = area of the square = a² Here a = 394 Therefore, the area of the garden = 394² = 394 × 394 = 155,236. The cost to tile the garden = 155,236 × 5 = 776,180. The total cost = 776,180 dollars
To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot.
So, the total cost is 776,180 dollars.
Find the area of a circle whose radius is 394 meters.
The area of the circle = 487,842.44 m²
The area of a circle = πr²
Here, r = 394
Therefore, the area of the circle = π × 394² = 3.14 × 394 × 394 = 487,842.44 m².
The area of the square is 155,236 cm². Find the perimeter of the square.
The perimeter of the square is 1,576 cm.
The area of the square = a²
Here, the area is 155,236 cm²
The length of the side is √155,236 = 394
Perimeter of the square = 4a
Here, a = 394
Therefore, the perimeter = 4 × 394 = 1,576 cm.
Find the square of 395.
The square of 395 is 156,025.
The square of 395 is multiplying 395 by 395.
So, the square = 395 × 395 = 156,025
