Anyone who lives in England will have no problem with identifying the flag of St. George whether they like football or not. But for those who may not be familiar, it is a white rectangle with a red cross on it. The red lines of the cross run horizontally and vertically about their respective centres (not across the corners).

So why am I telling you this? Ok, let's suppose we have a St. George flag measuring 4' x 3' and that the area of red (the cross) is the same as the area of white (the background).

What would be the width of the band making up the cross, assuming that the width of the band is the same, both vertically and horizontally?

This question was on my test and the answer was 3,272,500.

A tank is in the shape of a right circular cone of altitude 25 feet and base radius 20 feet with its vertex at the ground. (Think of an ice cream cone with its point facing down.) The tank is externally braced to prevent its falling over. If the tank is full of a fluid which weighs 50 pounds per cubic foot, find the work done, in foot pounds, correct to the nearest hundred footpounds, in pumping all of the fluid out of the top of the tank.

I know that the Volume of a cone= 1/3(pie)r^2h
I tried working the problem in the same manner as the spherical cylinder in the book except I used 1/3(pie) as opposed to just pie. I think the problem is my calculations of the radius being incorrect. The definite integral I came up with was

25
Int (1/3)(50)(pie)x(40-x)^2
0
as my r^2 of the ith interval was (40ci -ci^2)

Again help is greatly appreciated.

The altitude above sea level of an airplane just after taking off from an airport on a high pleteau is given by the linear function h(t) = 1000t + 3856, where h(t) is in feet and t is the time in minutes since take off. FInd the altitude of the airplane after 2 minutes.

Some one please explain this to me. I have been working on this problem for an hour.

It does not matter the size of a piece of paper - you can use a bed-sheet or a tarp or an A4 or letter sized piece of paper. Regardless, it cannot be folded in *half* more than eight times.
