How to Find Square Root of 394?
Value of √394 by Long Division Method
Explanation:
- Forming pairs: 03 and 94
- Find a number Y (1) such that whose square is <= 3. Now divide 03 by 1 with quotient as 1.
- Bring down the next pair 94, to the right of the remainder 2. The new dividend is now 294.
- 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 9) such that 2Z × Z <= 294. After finding Z, together 2 and Z (9) form a new divisor 29 for the new dividend 294.
- Divide 294 by 29 with the quotient as 9, giving the remainder = 294 - 29 × 9 = 294 - 261 = 33.
- Now, let's find the decimal places after the quotient 19.
- Bring down 00 to the right of this remainder 33. The new dividend is now 3300.
- Add the last digit of quotient to divisor i.e. 9 + 29 = 38. To the right of 38, find a digit Z (which is 8) such that 38Z × Z <= 3300. Together they form a new divisor (388) for the new dividend (3300).
- Divide 3300 by 388 with the quotient as 8, giving the remainder = 3300 - 388 × 8 = 3300 - 3104 = 196.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 394.
Therefore, the square root of 394 by long division method is 19.8 approximately.

Square Root of 394 Solved Examples
-
Example 1: Solve the equation x2 − 394 = 0
Solution:
x2 - 394 = 0 i.e. x2 = 394
x = ±√394
Since the value of the square root of 394 is 19.849,
⇒ x = +√394 or -√394 = 19.849 or -19.849. -
Example 2: If the area of an equilateral triangle is 394√3 in2. Find the length of one of the sides of the triangle.
Solution:
Let 'a' be the length of one of the sides of the equilateral triangle.
⇒ Area of the equilateral triangle = (√3/4)a2 = 394√3 in2
⇒ a = ±√1576 in
Since length can't be negative,
⇒ a = √1576 = 2 √394
We know that the square root of 394 is 19.849.
⇒ a = 39.699 in -
Example 3: If the area of a circle is 394π in2. Find the radius of the circle.
Solution:
Let 'r' be the radius of the circle.
⇒ Area of the circle = πr2 = 394π in2
⇒ r = ±√394 in
Since radius can't be negative,
⇒ r = √394
The square root of 394 is 19.849.
⇒ r = 19.849 in
