Answer:
The answer is below
Explanation:
The weight of trees is calculated using the equation:
[tex]W=b_o+b_1(D^2H)[/tex]
Where W is the weight in tons, [tex]b_o \ and\ b_1[/tex] are constants , D is the diameter of the tree in inches and H s]is the height of the tree in feet.
The circumference = 14 inches. But circumference = 2πr, where r is the radius and π = 22/7. Therefore:
14 = 2(22/7)× r
14 = (44/7)×r
r= 14 × 7 / 44 = 2.23 inches
Diameter = 2r = 4.45 inches
[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381b_1\\Let\ us\ assume\ b_o = -34.671,b_1=1.859.\\Therefore\\W = -34.671+2381(1.859)\\W=4392 \ tons[/tex]
