<u>Answer:</u></h3>
Average of salary of Anne and David is 1.25 of Peter's Salary
<h3>
<u>Explanation:</u></h3>
In the question, relations between salaries of Peter, Anne, and David is given. From the given relations, we need to make few equations and calculate the average of Anne and David in terms of Peter's Salary.
Let us assume Peter's Salary as P.
Then we can calculate Anne's salary A =
.
Also David's salary = D = 
Average of Anne's and David's salary = 
Average of Anne's and David's salary = 
Average of Anne's and David's salary = 
Average = 1.25 \times P
Volume of a Right circular cylinder=πr²h
Using "Cavaliers principle" or Just pire logic... it can be understood that...
if we were to cut of the base and top of the cylinder such that it will make up to be a right circular cylinder and join the other two pieces on top; We would obtain a Right circular cylinder With The same radius and height as the Given cylinder.
So;
Given. Base area B=81πcm²
also Base area =πr²
=>πr²=81π cm²
=>r=√81=9cm
Also Given;
Height h=3r
=>Height,h=3×9=27cm
So;Volume of cylinder V=πr²h ;(r²=81,h=27)
=>V=(81×27×22)/7
=>V=6867.18cm³ (approx.)
So,Required Volume =6867.18cm³(approx.)
Hope it helps...

Answer:
58 degrees
Step-by-step explanation:
90 - 32 = 58
15h^2 +10h +25 /5h = x +y +
15h^2 +10h +25/5h = 3h +2
15h^2
---------
0 10h
10h
------
0 25
so x=3h and y =2 than the 3rd choice is correct ,right sure
