Pythagorean Theorem. The Pythagorean theorem states that in any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs of the right triangle.

Answer:
30×pi ft
Step-by-step explanation:
ST is the diameter.
the formula for the circumference of a circle is
C = 2×pi×r
r = radius = diameter / 2
so,
C = 2×pi×30/2 = pi×30
therefore, the first answer option is correct.
