Answer:
Step-by-step explanation:
it is given that Square contains a chord of of the circle equal to the radius thus from diagram

If Chord is equal to radius then triangle PQR is an equilateral Triangle
Thus 
In triangle PQO applying Pythagoras theorem




Thus length of Side of square 
Area of square
Area of Circle
Ratio of square to the circle
Three-fourths of a number increased by one-half
= 3/4 x + 1/2
So three-fourths of a number increased by one-half is equal to fourteen:
3/4 x + 1/2 = 14
Multiply both sides by 4
3x + 2 = 56
Subtract 2 from both sides
3x = 54
Divide both sides by 3
x = 18
Answer: The number is 18
