Square root of 45 times square root of 45 = 45
3 times the square root of 5
45 is 9 times 5, and 9 is 3 squared, so the answer is 9 times the square root of 5.
The square root of 45, which you can easily get on any calculator.
No, nor is it a real number. The square root of minus 54 is equal to the square root of plus 45, times i.
45 is the square root of 2,025 (45 x 45 = 2025).
sqrt(1222) * 56/45 = 43.50219
You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.
The diagonal of the square is the diameter of the circle (think about it!) so the sides of the square can be pythagorassed ie the square of the diagonal is twice the square of a side. As an example, consider a circle of diameter 50 units. the square of this is 2500 so every side of the square is the square root of 1250 units which equals sqrt 625 x sqrt 2 or 25 root 2 ie 35.355339 units, or 70.71% of the diameter of the circle. More basically, the diagonal is the hypotenuse of a 45/45/90 triangle so the sides are in the ratio 1/1/root2 or if you want the hypotenuse to be 1, the sides would be (root 2)/2. Either way, the sides are root2 times the radius of the circle, which is of course half the diameter. This is in full agreement with the 25 root2 calculated above for a 50 unit diameter circle.
A 45-foot diameter circle has an area of 1,590.4 square feet.

The square root of 45 in simplest form is 3sqrt(5). You take the 2 roots from 45 (5 and 9) and find out the square root of 9 is 3, while the square root of 5 is still just square root 5.
