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 the topic, we will discuss the square of 802.
The square of a number is the product of the number itself.
The square of 802 is 802 × 802.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 802², where 802 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 802 is 802 × 802 = 643204.
Square of 802 in exponential form: 802²
Square of 802 in arithmetic form: 802 × 802
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 802
Step 1: Identify the number. Here, the number is 802
Step 2: Multiplying the number by itself, we get, 802 × 802 = 643204.
The square of 802 is 643204.
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 802
So: 802² = 802 × 802 = 643204
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 802.
Step 1: Enter the number in the calculator Enter 802 in the calculator.
Step 2: Multiply the number by itself using the multiplication button(×) That is 802 × 802
Step 3: Press the equal to button to find the answer
Here, the square of 802 is 643204.
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 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.
Find the length of the square, where the area of the square is 643204 cm².
The area of a square = a² So, the area of a square = 643204 cm² So, the length = √643204 = 802. The length of each side = 802 cm
The length of a square is 802 cm.
Because the area is 643204 cm² the length is √643204 = 802.
Sarah is planning to tile her square garden of length 802 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full garden?
The length of the garden = 802 feet The cost to tile 1 square foot of 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 = 802 Therefore, the area of the garden = 802² = 802 × 802 = 643204. The cost to tile the garden = 643204 × 5 = 3216020. The total cost = 3216020 dollars
To find the cost to tile the garden, we multiply the area of the garden by cost to tile per foot.
So, the total cost is 3216020 dollars.
Find the area of a circle whose radius is 802 meters.
The area of the circle = 2021672.64 m²
The area of a circle = πr²
Here, r = 802
Therefore, the area of the circle = π × 802² = 3.14 × 802 × 802 = 2021672.64 m².
The area of the square is 643204 cm². Find the perimeter of the square.
The perimeter of the square is 3208 cm.
The area of the square = a²
Here, the area is 643204 cm²
The length of the side is √643204 = 802
Perimeter of the square = 4a
Here, a = 802
Therefore, the perimeter = 4 × 802 = 3208.
Find the square of 803.
The square of 803 is 644809
The square of 803 is multiplying 803 by 803.
So, the square = 803 × 803 = 644809
