How to Find Square Root of 286?

Square Root of 286 by Long Division Method

Value of √286 by Long Division Method

Explanation:

Forming pairs: 02 and 86
Find a number Y (1) such that whose square is <= 2. Now divide 02 by 1 with quotient as 1.
Bring down the next pair 86, to the right of the remainder 1. The new dividend is now 186.
Add the last digit of the quotient (1) to the divisor (1) i.e. 1 + 1 = 2. To the right of 2, find a digit Z (which is 6) such that 2Z × Z <= 186. After finding Z, together 2 and Z (6) form a new divisor 26 for the new dividend 186.
Divide 186 by 26 with the quotient as 6, giving the remainder = 186 - 26 × 6 = 186 - 156 = 30.
Now, let's find the decimal places after the quotient 16.
Bring down 00 to the right of this remainder 30. The new dividend is now 3000.
Add the last digit of quotient to divisor i.e. 6 + 26 = 32. To the right of 32, find a digit Z (which is 9) such that 32Z × Z <= 3000. Together they form a new divisor (329) for the new dividend (3000).
Divide 3000 by 329 with the quotient as 9, giving the remainder = 3000 - 329 × 9 = 3000 - 2961 = 39.
Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 286.

Therefore, the square root of 286 by long division method is 16.9 approximately.

Square Root of 286 Solved Examples

Example 1: Solve the equation x² − 286 = 0

Solution:

x² - 286 = 0 i.e. x² = 286
x = ±√286
Since the value of the square root of 286 is 16.912,
⇒ x = +√286 or -√286 = 16.912 or -16.912.
Example 2: If the surface area of a sphere is 1144π in². Find the radius of the sphere.

Solution:

Let 'r' be the radius of the sphere.
⇒ Area of the sphere = 4πr² = 1144π in²
⇒ r = ±√286 in
Since radius can't be negative,
⇒ r = √286
The square root of 286 is 16.912.
⇒ r = 16.912 in
Example 3: If the area of a square is 286 in². Find the length of the side of the square.

Solution:

Let 'a' be the length of the side of the square.
⇒ Area of the square = a² = 286 in²
⇒ a = ±√286 in
Since length can't be negative,
⇒ a = √286 = 16.912 in
