Regardless of the size of the square, half the diagonal is (√2)/2 times the side of the square.
The ratio is (√2)/2.
_____
Consider a square of side length 1. The Pythagorean theorem tells you the diagonal measure (d) is ...
... d² = 1² +1² = 2
... d = √2
The distance from the center of the square to one of its corners (on the circumscribing circle) is then d/2 = (√2)/2. This is the radius of the circle in which our unit square is inscribed.
Since we're only interested in the ratio of the radius to the side length, using a side length of 1 gets us to that ratio directly.
Answer:
5:10
Step-by-step explanation:
Ans: $((18-6)÷3)
*It is a double-bracket because there is a bracketed equation inside a bracketed equation, so as to separate the values from the unit, in this case, the $ sign. Take 18-6 to find the total cost of the notepads, and take that value divided by 3, the price of one notepad, to find the number of notepads bought.
