Answer:
Step-by-step explanation:
surface area=top circle+bottom circle+straight face
top circle=bottom circle=pi(w-1)^2
straight face=length*height=circle circumference*height
=2pi(w-1)(w+3)
surface area=2pi(w-1)^2+2pi(w-1)(w+3)
=2pi(w-1)(w-1+w+3)
=2pi(w-1)(2w+2)
=4pi(w-1)(w+1)
Answer:
4π(w+1)(w-1)
Step-by-step explanation:
The total surface area of the cylinder
= 2 x area of base circle + area of vertical surface
= 2x pi x radius^2 + 2x pi x radius x height
= 2π(w-1)^2 + 2π(w-1)(w+3)
= 2π[w^2-2w+1 + w^2+2w-3]
= 2π(2w^2-2)
= 4π(w^2 - 1)
= 4π(w+1)(w-1)

Answer:
6x -16
Step-by-step explanation:
f(x) = 6x + 2
f(x-3) =
Replace x with x-3
f(x) = 6(x-3) + 2
Distribute
= 6x - 18 +2
= 6x -16
Answer:
5
Step-by-step explanation:
If Leilani has 5 apples, that means that Maggie has 10, but Maggie has 20 so that means that Adeline has 5 apples, because 5+5 is 10 and 10 doubled is 20

Answer:
f(x) = 5
Step-by-step explanation:
f(x) = 2x^2 - 3x+4
f(3) =2x^2 - 3x + 4
f(3) = 2(3)^2 - 3(3) + 4
f(3) = 18 - 13
f(x) = 5
Hope this helped :-)
