Question

What is the volume of a cylinder, in cubic cm, with a height of 19cm and a base diameter of 6cm? Round to the nearest tenths place

Answer 1

v = 537.2 cm3

Explanation:

volume:

`v=\pi r^(2) h`

`r=d/2=6/2=3cm`

`h=19cm`

`v=\pi (3)^(2) (19)=171\pi`

`v=537.21`

Rounded nearest tenth:

`v=537.2cm^(3)`

Hope this helps

Answer 2

volume of a cylinder = 536.9 cm³

Explanation:

volume of a cylinder, V = πr²h

where π = 3.14

h = 19 cm

r = ?

given is diameter = 6 cm

as we know, r = d/2 = 6/2 = 3 cm

by substituting the values in the formula,

V = 3.14 * 3² * 19

= 536.94 cm³

by rounding off to the nearest tenth place,

volume of a cylinder = 536.9 cm³
