How to Find Square Root of 3721?
Value of √3721 by Long Division Method
Explanation:
- Forming pairs: 37 and 21
- Find a number Y (6) such that whose square is <= 37. Now divide 37 by 6 with quotient as 6.
- Bring down the next pair 21, to the right of the remainder 1. The new dividend is now 121.
- Add the last digit of the quotient (6) to the divisor (6) i.e. 6 + 6 = 12. To the right of 12, find a digit Z (which is 1) such that 12Z × Z <= 121. After finding Z, together 12 and Z (1) form a new divisor 121 for the new dividend 121.
- Divide 121 by 121 with the quotient as 1, giving the remainder = 121 - 121 × 1 = 121 - 121 = 0.
- We stop the process since the remainder is now 0 and there are no more digits that can be brought down.
Therefore, the square root of 3721 by long division method is 61.

Example 2: If the area of a circle is 3721π in2. Find the radius of the circle.
Solution:
Let 'r' be the radius of the circle.
⇒ Area of the circle = πr2 = 3721π in2
⇒ r = ±√3721 in
Since radius can't be negative,
⇒ r = √3721
Square root of 3721 is 61.
⇒ r = 61 in -
Example 3: If the area of an equilateral triangle is 3721√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 = 3721√3 in2
⇒ a = ±√14884 in
Since length can't be negative,
⇒ a = √14884 = 2 √3721
We know that the square root of 3721 is 61.
⇒ a = 122 in
