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).
You would only be able to calculate if the area was a perfect square. If the length and width were different, then you would need to know at least one of the dimensions. 1/3 acre = 14520 square feet. If a perfect square: 120.5 feet * 120.5 feet = 14520 square feet. If its rectangle in shape you need to know at least one dimension, the length or width. Comment.
