Answer :
The diameter of the circle is 19.8 inches.
We are given the value of side of square in the question. The diameter of the circle will be equal to the diagonal of square. The diagonal of square can be calculated using Pythagoras theorem. So, finding the diagonal of square, which will be hypotenuse.
Diagonal² = Base² + Perpendicular²
Diagonal² = side² + side²
Keep the values to find the value of diagonal
Diagonal² = 14² + 14²
Take square of values on Right Hand Side of equation
Diagonal² = 392
Diagonal = √392
Taking square root on Right Hand Side of equation
Diagonal = 19.8 inch
So, diagonal of square is diameter of circle which is 19.8 inches.
