Answer:
c)A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
Step-by-step explanation:
A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
The volume of a cylinder is given by V=Bh or V=πr²h
where B is the area of the base and h is the height of the cylinder.
V=πr²h-------equation1
V= π(w³ +2w² )--------- equation2
Comparing equation 1 and equation 2
πr²h=π(w³ +2w² )
r²h=(w³ +2w² )
r²h= w²(w +2 )
Taking w² common leaves w+2 which gives the height or length of the cylinder.
Therefore radius = width and height = length which gives the volume of the cylinder.

Answer:
V = 5 m/h
Step-by-step explanation:
An aircraft carrier, traveled 9 hours at speed of 25 mph, that means the aircraft position from Hawaii (the start point of the journey) is:
25 m/h * 9 h = 225 miles far away from hawaii
When the aircraft has traveled 9 hours, the submarine has traveled 11 hours ( since its departure was 2 hours earlier ). They both traveled in opposite directions.
Then distance between the two vessels = d
d = 280 miles
280 = 225 miles (from the aircraft to hawaii ) + traveled distance for the submarine
And
Traveled distance by submarine d(s) = V* 11 miles/hour. where V is speed of submarine
Then
280 = 225 + 11*V ⇒ 11*V = 280-225 ⇒ 11*V = 55/11 mph
V = 5 m/h
Answer:
5/w -7
