How to Find Square Root of 772?
Value of √772 by Long Division Method
Explanation:
- Forming pairs: 07 and 72
- Find a number Y (2) such that whose square is <= 7. Now divide 07 by 2 with quotient as 2.
- Bring down the next pair 72, to the right of the remainder 3. The new dividend is now 372.
- 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 7) such that 4Z × Z <= 372. After finding Z, together 4 and Z (7) form a new divisor 47 for the new dividend 372.
- Divide 372 by 47 with the quotient as 7, giving the remainder = 372 - 47 × 7 = 372 - 329 = 43.
- Now, let's find the decimal places after the quotient 27.
- Bring down 00 to the right of this remainder 43. The new dividend is now 4300.
- Add the last digit of quotient to divisor i.e. 7 + 47 = 54. To the right of 54, find a digit Z (which is 7) such that 54Z × Z <= 4300. Together they form a new divisor (547) for the new dividend (4300).
- Divide 4300 by 547 with the quotient as 7, giving the remainder = 4300 - 547 × 7 = 4300 - 3829 = 471.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 772.
Therefore, the square root of 772 by long division method is 27.7 approx.

Square Root of 772 Solved Examples
-
Example 1: Solve the equation x2 − 772 = 0
Solution:
x2 - 772 = 0 i.e. x2 = 772
x = ±√772
Since the value of the square root of 772 is 27.785,
⇒ x = +√772 or -√772 = 27.785 or -27.785. -
Example 2: If the area of an equilateral triangle is 772√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 = 772√3 in2
⇒ a = ±√3088 in
Since length can't be negative,
⇒ a = √3088 = 2 √772
We know that the square root of 772 is 27.785.
⇒ a = 55.570 in -
Example 3: If the surface area of a sphere is 3088π in2. Find the radius of the sphere.
Solution:
Let 'r' be the radius of the sphere.
