Question

if a circle with a circumference of 16pi inches is circumscribed about a square what is the length of a diagonal of the square​

Answer 1

8 inches

Explanation:

Circumference is 2pi*r, so this makes the radius of the circle be 8, which means the diameter of the circle is 16. The diameter is the same length as the diagonal of the square, so the diagonal of the square is 8 inches.
