Step-by-step explanation:
I) 9+9+9+9=36
Ii)radius is 4.5 L=2piR= 2pi(4.5)= 9pi
Iii) A=piR^2= pi(4.5)^2 = 20.5pi
IV) 9×9 =81
V) 81-20.5pi = 16.597
Answer:
8
Step-by-step explanation:
Hello,
This is related to ratios and proportions. We have a 12 foot tree that casts a 6 foot shadow, so now we are trying to figure out how tall is a tree that casts a 4 foot shadow.
We can set an easier method to get this.
12 = 6 (this means the 12 foot tree casts a 6 foot shadow)
x = 4 (this means how tall is the tree to cast a 4 foot shadow, the unknown height of the tree is denoted as x)
Then, we can cross multiply.
48 = 6x
Solve for x, which is the unknown height we are trying to figure out.
x = 8
9.2*14.71
=135.332
This is to 3 decimal places
