Question 1094000: The cross-sectional area of a certain tree is a linear function of time. If the radius of this circular cross-section was 2 feet in 1915 and 3 feet in 1990, what was it's radius in 2005? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! The cross-sectional area of a certain tree is a linear function of time. If the radius of this circular cross-section was 2 feet in 1915 and 3 feet in 1990, what was it's [sic] radius in 2005?
----------------
(3-2)/(1990 - 1915) = 1/75 ft/yr
-----
In 2005:
3 + (2005 - 1990)*1/75 feet
====================
PS it's = it is
