Step 2: Multiply the number by itself using the multiplication button (×) That is 386 × 386
Step 3: Press the equal to button to find the answer
Here, the square of 386 is 148996.
Tips and Tricks for the Square of 386
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 386
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 386² with (3 + 8 + 6)² or (380 + 6)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 386
Problem 1
Find the length of the square, where the area of the square is 148996 cm².
The area of a square = a² So, the area of a square = 148996 cm² So, the length = √148996 = 386. The length of each side = 386 cm
Explanation
The length of a square is 386 cm.
Because the area is 148996 cm², the length is √148996 = 386.
Problem 2
Sarah wants to lay tiles on her square patio of length 386 feet. The cost to lay a tile per square foot is 3 dollars. Then how much will it cost to tile the full patio?
The length of the patio = 386 feet The cost to lay 1 square foot of tile = 3 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 = 386 Therefore, the area of the patio = 386² = 386 × 386 = 148996. The cost to tile the patio = 148996 × 3 = 446988. The total cost = 446988 dollars
Explanation
To find the cost to tile the patio, we multiply the area of the patio by the cost to lay per square foot.
So, the total cost is 446988 dollars.
Problem 3
Find the area of a circle whose radius is 386 meters.
The area of the circle = 467,733.12 m²
Explanation
The area of a circle = πr²
Here, r = 386
Therefore, the area of the circle = π × 386² = 3.14 × 386 × 386 = 467733.12 m².
Problem 4
The area of the square is 148996 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 148996 cm²
The length of the side is √148996 = 386
Perimeter of the square = 4a
Here, a = 386
Therefore, the perimeter = 4 × 386 = 1544.
Problem 5
Find the square of 387.
The square of 387 is 149769
Explanation
The square of 387 is multiplying 387 by 387.
So, the square = 387 × 387 = 149769
