calculate the volume of this cylinder, give your answer to 1 decimal place

Answer:
V ≈ 2827.4 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius of the base and h is the height )
Here diameter = 20 , so radius r = 20 ÷ 2 = 10 , h = 9 , then
V = π × 10² × 9
= π × 100 × 9
= 900π
≈ 2827.4 cm² ( to 1 dec. place
Answer:
2,826 [tex]cm^3[/tex]
Step-by-step explanation:
The formula for finding the volume of cylinder is V=πr^2h
height = 9 cm.
radius ( half of diameter)
20 ÷ 2 = 10
π = 3.14
Insert the values in the formula
[tex]V=πr^2h\\V=(3.14)(10^2)(9)\\V = (3.14)(100)(9)\\V = 2,826 cm^3[/tex]
