- First of all, a 2 foot kangaroo is casting a 7 foot shadow.
- Next we do 7 divided by 2 which equals 3.5.
- Since we know the shadow is going to be 3.5x the object size we have to divide its shadow by 3.5
- 14 divided by 3.5 is  4 so the Eucalyptus tree is 4ft long
 
<u><em>    Your answer=4ft </em></u>

Hey there! 
 Formula: πr^2
r = radius 
pi = 3.1415926535898 (but we can say it approximately equals 3.14)
Your equation (3.14)(4.2)^2 = answer
4.2^2 = 4.2 × 4.2 = 17.64 
New equation: 17.64 × 3.14 = 55.3896 
We round our answer to the nearest tenth 
Answer: 55.4 ☑️
Good luck on your assignment and enjoy your day!

Answer:
$17.50
Step-by-step explanation:
Multiply 7/8 by 20/1, to find 7/8 of $20.00. 
7/8 × 20/1 = 140/8
140 ÷ 8 = 17.5
Once you convert to money, this is $17.50.
