What is the intersecting volume of two pipes?

Okay let's try a hard question for a change.

What is the volume of intersection of two pipes whose center axes intersect each other at a perfect right angle, and whose inner diameters are 1 meter? That is, what is the total volume of the set of points which are enclosed by both pipes at the same time?

Hint. Consider the pipes as the equations z^2+x^2=0.25 and z^2+y^2=0.25 .

How do you use vectors to solve questions of force?

For example, if I was to have a truck weighing 6578 pounds on a driveway inclined at 17.5 degrees, what's the magnitude of the force required to keep the truck still?

I do know that the force of gravity on the truck is 6578sin(17.5), but I have no idea on how to find the force required to counteract the gravity.

math word problem?

Get your checkerboard and place one grain of wheat on the first square. Then place two grains of wheat on the next square. Then place four grains on the third square. Continue this until all 64 squares are covered with grains of wheat.” As he had just harvested his wheat, Mr. Crane did not consider this much of an award, but he soon realized he made a miscalculation on the amount of wheat involved.

How much total grain would the traveling salesman receive if the checkerboard only had 24 squares?
Calculate the amount of wheat necessary to fill the whole checkerboard (64 squares). How much wheat would the farmer need to give the salesman? Please provide the answer in either scientific notation, or calculate and show all 20 digits.
