Answer 1

By definition, the volume of a cylinder is given by:

$V = \pi * r ^ 2 * h$

Where,

r: cylinder radius.

h: cylinder height

Substituting values in the given equation we have:

$V = 3.14 * (\frac{13}{2}) ^ 2 * 11\\V = 1459,315$

Rounding to the nearest tenth we have:

$V = 1459.3 cm ^ 3$

Answer:

The volume of the cylinder is:

$V = 1459.3 cm ^ 3$

option 4

Answer 2

$V = \pi r^2 h$

$r = \frac 1 2 (13 \textrm{ cm})$

$h = 11 \textrm{ cm}$

$V = 3.14 (13/2)^2 (11) = 1459.315$
