Question

→ 12 cm.

Answer 1

Answer:

Step-by-step explanation:

CONE:

height of cone = h =  12 cm

r =3.5 cm

$Volume \ of \ cone =\dfrac{1}{3}\pi r^{2}h$

                           $=\dfrac{1}{3}*\dfrac{22}{7}*3.5*3.5*12\\\\\\=22*0.5*3.5*4\\\\= 154 \ cm^{3}$

Cylinder:

h = 16 cm

r = 3.5 cm

$Volume \ of \ cylinder = \pi r^{2}h$

                                $= \dfrac{22}{7}*3.5*3.5*16\\\\\\= 22*0.5*3.5*16\\\\= 616 \ cm^{3}$

Total volume = 154 + 616

                       = 770 cm³
