What is the circumference of a circle in which a 5 by 12 rectangle is inscribed?

13pi. The length of a diagonal of a 5 by 12 rectangle is 13 (pythagorean theorem). The diagonal of the rectangle is the diameter of the circle inscribed, and C = 2(pi)r.

The height h of a cylinder equals the circumference of the cylinder. In terms of h, what is the volume of the cylinder?

(h^3)/4pi. h=2(pi)r, so r=h/2pi. Volume of cylinder = pi(r^2)h = pi[(h/2pi)^2]h = (h^3)/4pi.

If the integer lengths of the three sides of a triangle are 4, x, and 9, what is the least possible perimeter of the triangle?

19. In the given triangle, 9-4

500

What is the number of sides of a polygon in which the sum of the degree measures of the interior angles is 4 times the sum of the degree measures of the exterior angles?

10. Sum of the degree measures of exterior angles is 360. S = (n-2)180 = 4 x 360, where n=number of sides. Solving for (n-2) = 8 or n=10.

Your guess is as good as mine.
