Missing information:

r = 3cm

h = 1cm

Options:

(a)
$\pi * 3^2 * 15$ (b)
$\pi * 3* 15^2$

(c) 15 times the volume of the disk

(d) The height of the stack multiplied by
$\pi r^2$

Answer:

(b)
$\pi * 3* 15^2$

Explanation:

Given

15 identical disks

r = 3cm

h = 1cm

Required

Determine the odd option

The volume of 1 disk is:

$V_1 = \pi r^2h$

$V_1 = \pi * 3^2 * 1$

The volume of 15 is:

V_(15) = 15 * V_1

$V_(15) = 15 * \pi * 3^2 * 1$

$V_(15) = \pi * 3^2 * 15$

The above equation represents (a), (c) and (d)

Because:

(a):
$V_(15) = \pi * 3^2 * 15$

(c) 15 * volume of the disk:
V_(15) = 15 * V_1 =
$V_(15) = \pi * 3^2 * 15$

(d) height *
$\pi r^2$ = h *
$\pi r^2$ =
$15 * \pi * 3^2 * 1$ =
$V_(15) = \pi * 3^2 * 15$

Hence, (b) is the odd option
