	Two great circles		2011-10-06
		Jean pose la question : "Two great circles lying in planes that are perpendicular to each other are drawn on a wooden sphere of radius "a". Part of the sphere is then shaved off in such a way that each cross section of the remaining solid that is perpendicular to the common diameter of the two great circles is a square whose vertices lie on these circles. Find the volume of this solid." I don't understand the geometry of the problem. Can you please explain the problem and if possible draw a diagram for me ? Chris Fisher lui répond.

	Surface area of a dome		2009-09-16
		Charlie pose la question : Why is the calculation for the surface area of a domed tank less than the surface area of a flat top tank. Using domed tank formula 2*pi*r(r-(r-dome ht) works out to be less surface area than a flat top tank area formula pi*r x r, Shouldn't the dome have more surface area than the flat surface ? Harley Weston lui répond.
	A spherical dome		2009-08-03
		Eric pose la question : I have recently been asked to resurface a dome sculpture for my local council but i'm having problems working out the area. Here are the dimensions. The height of the dome is 3m from the ground to the top of the arc. The arc itself from the ground rising up to the 3m point and back down, is 10m. The dome is 7m wide from one side to the other through the centre, at ground level. I hope there is enough detail here. It's been a long time since i was in a maths class. Thank you, hope to here from you soon! Stephen La Rocque lui répond.
	Two circles on a dome		2009-07-01
		Beth pose la question : My question is related to a dome I would like to construct, for which I know the circumference of the base: 120ft. I now need to figure out the diameters of two smaller circles, one at 20ft along the arc of the dome form the ground, and the other at 30ft along the arc. Assuming a true hemisphere, or 180 degrees total arc, how can I calculate these two circumferences? Beth Stephen La Rocque lui répond.
