Step-by-step explanation:
Circumference of a white oak tree:
C = 90 in.
C = 2 r π
2 r π = 90
r · 6.28 = 90
r = 90 : 6.28
r = 14.33 in ( but it is not r in the formula )
Since the bark is 0.5 in thick: r = 14.33 - 0.5 = 13.83 in
a = r : w = 13.83 : 0.2 = 69.15 years
The widest ring is one that shows 69 years:
r = 69 · 0.2 = 13.8 in
A = r² π = 13.8² · 3.14 = 190.44 · 3.14 = 597.98 in²
Answer: The tree`s age is 69.15 years ( or 69 years and 2 months ) and the area enclosed by the outer circumference of the widest ring is 597.98 in².
Answer:
45 i believe
Step-by-step explanation:
Doubling the linear dimensions (side lengths) of any figure doubles its perimeter and quadruples (x 4) its area. If its a 3-D (solid) figure, its volume multiplies by 8 .
We are given the results of an election:
Candidate Fraction of votes
Johnson =
Smith =
Dragovic =
Now, we need to find the difference between the fractions of votes received by Dragovic and Johnson.
Therefore, difference is :
Taking common denominator of 2 and 9 is 18.
<h3>Therefore, the difference between the fractions of votes received by Dragovic and Johnson is
.</h3>
