The element silicon is used extensively as a semiconductor in solid-state devices in the computer and microelectronics industries. For this, hyperpure silicon is needed. The silicon is selectively doped with tiny amounts of boron, gallium, phosphorus or arsenic to control its electrical properties.
Â· just now. Asker's rating. Report Abuse. An acre is a measure of area that I will call A for now. L*W = A which gives L = A/W C = 2*(L + W) = 2*(A/W + W) So, as you can see, the circumference depends on the width (or L, whichever way you want to look at it).
That's if it's a square, with sides = 208.7 feet. If the 1-acre is a rectangle but not a square, then the sides can be anything. longer than 208.7 feet. It only depends on how long and skinny the rectangle. is. Here are a few examples. All of the rectangles on this list enclose 1 acre: 220' x 198'.
