Part 1)which is the correct first step in finding the height of a cylinder with a volume of 178 pie cubic inches and a radius of 8 inches

we know that
[volume of a cylinder]=pi*r²*h
volume =178 pi in³
r=8 in
178 pi in³=pi*8²*h

the answer Part 1) is 
178pie=pie(8)^2h

Part 2) Louis calculated the height of a cylinder that has a volume of 486pie cubic centimeters and a radius of 9 centimeters her work is shows below
V=BH
STEP 1:486pie=pie9^2h
STEP 2:486pie=81pieh
STEP 3:486pie/81pie=81pie/81pie h
STEP 4:h=6pie cm
what error did louise make when calculating the height of the cylinder

 we know that
[volume of a cylinder]=pi*r²*h
volume =486 pi cm³
r=9 cm
486pi=pi*9²*h> step 1 is correct
486pi=pi*81*h> step 2 is correct
486pi/81pi=pi*81*h/81pi> step 3 is correct
h=6 cm> step 4 is nor correct, because the pi factor is canceled

therefore 

the answer part 2) is
C.in step 4 the pie should have canceled making the correct answer 6 cm

Part 3)which is the correct first step in finding the area of the base of a cylinder with a volume of 140 pie cubic meters and a height of 12 meters

we know that
[volume of a cylinder]=area of the base*height 
B=area of the base
volume=140pi m³
h=12 m
140pi=B*12
therefore

the answer Part 3) is
140pie=B(12)

Part 4) the volume of a cylinder can be found using the formula V=pie^2h
which is the correct first step in finding the height of a cylinder with a volume of 192pie cubic inches and a radius of 5 inches

we know that
V=pi*r²*h
V=192pi in³
r=5 in
192pi=pi*5²*h

therefore
the answer Part 4) is
D.192pie=pie(5)^2h

Part 5)a cylinder has a volume of 140pie cubic meters and a height of 14 meters what is the area of the base
we know that
[volume of a cylinder]=area of the base*height 
area of the base=Volume/height > 140pi/14> 10pi m²

the answer Part 5) is
A.10pie square meters
