Answer:
required formula: πr^2h
Solution
Formula to find volume of cylinder= πr^2h
= 22/7 ×3×3×4
= 113.14cm^3
Mr.Avila's classroom would be bigger because 1/6 is bigger than 1/8.
Hey there! :D
In the fraction 1/8, the denominator is 8. There are 8 of these parts or “fractions” in 1. So, multiply that by 25.
8*25= 200
There are 200 1/8s in 25.
I hope this helps!

The only way I can envision this is put all 4 points on 1 line segment. They go in the order of ADCB. I can only draw it this one way.
Given
D is the midpoint of AC
C is the midpoint of DB
AC = 3 cm
Argument
AC = 3 cm Given
AD = DC D is the midpoint of AC
AD = 3/2 Definition of a midpoint.
DC = 3/2 Definition of a midpoint
DC = 3/2 Last statement
DC + CB = 1.5 + 1.5. C is the midpoint of BD
DB = 3 Consolidation of equals
AD + DB = AB
1.5 + 3 = 4.5 Substitution.
<h3>Answer: 395 birds</h3>
==============================================
Work Shown:
The formula to use is
A = P*(1+r)^x
where,
P = 12000 is the initial population
r = -0.15 represents the growth rate in decimal form; which is really a decay/decrease due to r being negative
x = 21 days have passed by (3 weeks = 3*7 = 21 days)
These values lead to...
A = P*(1+r)^x
A = 12000*(1+(-0.15))^21
A = 12000*(1-0.15)^21
A = 12000*(0.85)^21
A = 12000*0.03294560142183
A = 395.34721706196
A = 395
