Answer:
22 feet²
Step-by-step explanation:
We are given:
height of tree h = 45 inches
Circumference= πd × inches
But d = 22.2inches
Therefore area will be
Area = 22.2π × 45 inches²
Area = 3137 inches²
Let's convert from inches² to feet², we have:
1 foot = 12 inches.
Therefore,
1 square foot = 1foot × 1foot = 12inches×12inches
= 3137inches² / 144 inches²
= 22feet²
Note: I attached missing data which states that diameter at year 13 is 22.2inches

Answer:
4
Step-by-step explanation:
Lets make be the ? in the equation.
That becomes ( x 3) - 3 = 15.
First you have to add 3 on both sides. After doing that it gets to ( x 3) = 15 - 3.
Then you simplify it to 3 = 12.
Now you divide 3 on both sides. That gets to = 4 after doing it.
