ok so what you do is find area of total-areapond=areaaround
then times that by the height
areatotal=pir^2
r=7.5+2=9.5
aeratotal=pi9.5^2=90.25pi
areapond=pi7.5^2=56.25pi
areaaround=90.25pi-56.25pi=34pi
volume=area times height
34pi m^2
15 cm thick
convert 15cm to m
0.15m
34pi times 0.15=5.1pim^3=16.02m^3
volume=16.0 m^3
if converted to cm
v=16022122.5 cm^3
<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>When we substitute the values in (x,y) form, we are basically checking to see if the statement is true or not.</u>
- => 1 < 8(10) + 1
- => 1 < 81
<u>Hence, this statement satisfies the inequality.</u>
Hoped this helped

Final result :: (2x + 3y) • (2x - 3y)
Let b>a...
b=2(a+4)
b=2a+8 then we are told that:
b-a=11 using b found above in this equation gives you:
2a+8-a=11 combining like terms on left side
a+8=11 subtracting 8 from both sides
a=3
So the smaller number is 3.
...
since b=2a+8
b=14
check..
b=2(a+4)
14=2(3+4)
14=2(7)
14=14
and
b-a=11
14-3=11
11=11
