In 54.374 the nearest hundredth relates to the .374 part. The nearest hundred to 374 is 400. So the answer is 54.400 or 54.4
To answer that definitively, we'd have to know the value of xz. When rounding to a specific place, take a look at the digit immediately to the right of the target, in this case, the thousandths place. If that digit is 4 or less, zero everything to the right of the target out. If that digit is 5 through 9, increase the target by one and zero everything to the right of it out. If the target is a 9, increasing it will turn it to zero and increase the digit to the left of the target by one.

0.995 inches rounded to the nearest tenth of an inch is 1.0 inch.

IF the window is four-sided, the area is the length times the width. To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, the tenths place. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.

The perimeter is 2 times the length plus 2 times the width.
There are 2.54 centimetres in one inch. Therefore, one hundredth of an inch is equal to 2.54 / 100 = 0.0254 centimetres.

If the radius is 4, the width is 8 inches. If it is a 4 inch circle diametrically the width is 4 inches
0.995 inches rounded to the nearest tenth of an inch is 1.0 inch.
To round any number, look at the digit to the right of the place you are rounding to. If the digit is 5 or more, change the digit in the place you are rounding to to the next higher digit. If the digit to the right of the place you are rounding to is less than 5, leave the digit in the place you are rounding to as it is. Change all digits to the right of the place you rounded to to zeros.
I would say that 1/2 inch is nearest.
42/2pi is 6.68 inch radius
