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).
If you have a perfect square that is equal to 1 acre, what is the length of the sides and how do you do it? One acre is 43,560 square feet so a square, with area one acre would have a side if length the square root of 43,560 or approximately 208.71 feet. That is. 208.71feet 208.71feet = 43559.86 square feet. Penny.
