A rectangle has two dimensions - length and width.

Only if both dimensions are doubled, then the perimeter will be doubled.

the radius is from the center of the circle to the edge so that's how you find the radius.

It shows that the thing is bigger then what it is and they know that the decimal is rounded and they also know that it will have a decimal in it

The confidence intervals will increase. How much it will increase depends on whether the underlying probability model is additive or multiplicative.

An error in measuring the radius (or diameter) of the cylinder has a greater effect on the accuracy of the volume calculation than an error in measuring the cylinder's length, since the volume is proportional to the square of the radius.

Let's take a look at this problem.Rectangle Perimeter = 2(l + w)Rectangle Perimeter =? 2(2l + 2w)Rectangle Perimeter =? (2)(2)(l + w)2(Rectangle Perimeter) = 2[2(l + w)]Thus, we can say that the perimeter of a rectangle is doubled when its dimensions are doubled.Rectangle Area = lwRectangle Area =?

Since the perimeter is a linear measure it is also doubled.

When all of the linear dimensions are doubled . . .-- the perimeter is also doubled-- the area is multiplied by 22 = 4.

The effect on the total surface area of one dimension being doubled or tripled cannot be calculated. You either need to know all three dimensions or all three dimensions must be doubled, not just one dimension (or demension / demansion as you call them).
