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]
