Diameter of 6x and height of 2x+5 what is the volume of the cylinder
2 answers:
Answer:
(18x^3 + 45x^2)π unit^3.
Step-by-step explanation:
The radius of the base = 1/2 * 6x = 3x.
The volume = π r^2 h
= π * (3x)^2 * (2x + 5)
= 9x^2(2x + 5) π
= (18x^3 + 45x^2)π.
Answer:
V = pi*x^2*(18x - 45)
Step-by-step explanation:
If the diameter is 6x and the height is 2x + 5, we know that the radius is 3x.
Plugging this info into the volume-of-a-cylinder formula V = pi*r^2*h, we get:
V = pi*(3x)^2*(2x - 5), or V = pi*(9x^2)(2x -5), or:
V = pi*(18x^3 - 45x^2), or V = pi*x^2*(18x - 45)

Answer:
would it be 130?
Step-by-step explanation:
because 40+90=130 then 180-130=50 so 1=50 and that means 3 is 50 too. so then you would subtract 50 from 190 which is 130.

Answer:
7 shirts
Step-by-step explanation:
You first have to subtract 22 from 80, since that's how much she already spent, 80-22=58. Now you have to do 58/8, but since 8 doesn't divide evenly into 58, you have to go with the closet multiple of 8 which would be 56. 7x8=56, so Jenna can buy a maximum number of 7 shirts.
Answer:
= 2+10²× 1
= 2+(10*10)× 1
= 2+100×1
= 2+100
=102
Answer:
-750
Step-by-step explanation:
Q(h)=-8h^2-5h ,
Let x = -10
q(-10) = -8 (-10)^2 -5(-10)
=-8 *100 +50
=-800+50
= -750
