How to Find Square Root of 486?
Value of √486 by Long Division Method
Explanation:
 Forming pairs: 04 and 86
 Find a number Y (2) such that whose square is <= 4. Now divide 04 by 2 with quotient as 2.
 Bring down the next pair 86, to the right of the remainder 0. The new dividend is now 86.
 Add the last digit of the quotient (2) to the divisor (2) i.e. 2 + 2 = 4. To the right of 4, find a digit Z (which is 2) such that 4Z × Z <= 86. After finding Z, together 4 and Z (2) form a new divisor 42 for the new dividend 86.
 Divide 86 by 42 with the quotient as 2, giving the remainder = 86  42 × 2 = 86  84 = 2.
 Now, let's find the decimal places after the quotient 22.
 Bring down 00 to the right of this remainder 2. The new dividend is now 200.
 Add the last digit of quotient to divisor i.e. 2 + 42 = 44. To the right of 44, find a digit Z (which is 0) such that 44Z × Z <= 200. Together they form a new divisor (440) for the new dividend (200).
 Divide 200 by 440 with the quotient as 0, giving the remainder = 200  440 × 0 = 200  0 = 200.
 Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 486.
Therefore, the square root of 486 by long division method is 22.0 approx.

Square Root of 486 Solved Examples

Example 1: Solve the equation x^{2} − 486 = 0
Solution:
x^{2}  486 = 0 i.e. x^{2} = 486
x = ±√486
Since the value of the square root of 486 is 22.045,
⇒ x = +√486 or √486 = 22.045 or 22.045. 
Example 2: If the surface area of a cube is 2916 in^{2}. Find the length of the side of the cube.
Solution:
Let 'a' be the length of the side of the cube.
⇒ Area of the cube = 6a^{2} = 2916 in^{2}
⇒ a = ±√486 in
Since length can't be negative,
⇒ a = √486
We know that the square root of 486 is 22.045.
⇒ a = 22.045 in 
Example 3: If the surface area of a sphere is 1944π in^{2}. Find the radius of the sphere.
Solution:
Let 'r' be the radius of the sphere.
⇒ Area of the sphere = 4πr^{2} = 1944π in^{2}
⇒ r = ±√486 in
Since radius can't be negative,
⇒ r = √486
The square root of 486 is 22.045.
⇒ r = 22.045 in
FAQs on the Square Root of 486
What is the Value of the Square Root of 486?
