Answer:
V= 452.39cm³ (to 2 d.p. )
S.A. = 326.73cm² (to 2 d.p. )
Step-by-step explanation:
Vcylinder = π r² h = π (4)² (9) = 144 π = 452.3893421cm³ = 452.39cm³ (to 2 d.p. )
S.A. cylinder = 2π r h + 2π r² = 2π (4)(9) + 2π (4)² = 104π = 326.725636cm² = 326.73cm² (to 2 d.p. )

True
Answer:
Range = {0,2/3,1 1/3, 2, ...}
Step-by-step explanation:
The range is the output so the y values, when x = 3 then
y = 
(3) - 2 so y = 0
y = (4) - 2 so 8/3 - 6/3 is 2/3 so y = 2/3
y = (5) - 2 so 10/3 - 6/3 is 4/3 so y = 4/3 or 1 1/3
y = (6) - 2 so 12/3 - 6/3 is 6/3 so y = 2 and so on....
Now you try the rest
