The longest chord is 16, the short one is 12.\n\nFirst, for those of you playing along at home, here is the picture.\n\nDraw the large circle (radius 10) centered at (0,0), the small circle (radius 3.5) centered at (12.5,0). Draw chord in the large circle at (6,0), the chord in the small circle at (10,0). These are both vertical lines.\n\nLook at the large circle first. Half of the cord is one leg of a triangle with a hypontenuse of 10 (radius of the circle and a leg of 6 (10 - 4 overlap). This is a 6, 8, 10 (3,4,5) right triangle, so half the length of the chord is 8, its length is 16.\n\nNow look at the small circle. Half of the cord is one leg of a triangle with a hypontenuse of 6.5 and one leg of 2.5,\nthis is half of a 5,12,13 right triangle so the other leg is 6, the length of the chord is 12.

The trick is turning the word problem into equations.\n(Key: length = l; width = w)\n\nThey tell you the length is 3 feet more than twice the width, so:\nl = 2w + 3\n\nThen they tell you the perimeter (which is twice the width and twice the length) is 36, so:\n2l + 2w = 36\n\nYou should be able to take it from there.

triangle area = 1/2(height * width)\n\ncircle area = pi * radius^2

Simply equate gravity function with centripetal acceleration.\n\nGMe/(r+h)^2 = V^2/(r+h)....where r is earth radius and h is height\n\nsolve for v

Quadrilateral..........D is the correct answer.....

Just add up the lengths of the three sides. Works for any triangle - wether it's equilateral, isosceles or obtuse.

You are missing a constraint in your problem.  If your only constraints are \n- theta must be less than or equal to pi/2 \n- you want to maximize theta\nthen theta = pi/2.\n\nSo how far should you be?  0 meters.

The only thing I remember about geometry is...a2 + b2 = c2.\n\nSomehow, I doubt that helps you.....sorry.

Diameter == 10.\nRadius == 5.\nCenter == (1,7)\n\nMethod: use Pythagorean Theorem.

A quick guess without having reviewed your math, try adding g = 9.8 m/sec^2 to your answer and see if that is the answer that is needed.

You can get any geometric conversion by simply typing the question into the Google search box. I just did this, entering "800 cubic meters in cubic feet" and got the answer: 28, 251.7334 cubic feet.  Cool!\n\nGood luck!!

Half of the diameter.\n\nor\n\nMeasure around it.  Divide that number by 3.14.  Then divide by 2.
