Answer 1

Hi buddy!!!!!!

Here is the answer ------------

d=24cm

r=d/2=24/2=12cm

h=3.5cm

volume of cone=1/3πr^2h
=1/3x22/7x12^2x3.5
=1/3x22x144x0.5
=1x22x48x0.5
=528 cm^3

Answer 2

$volume \: of \: cone \: = \: \frac{1}{3}\pi {r}^{2} h \\ = \frac{1}{3} \times \frac{22}{7} \times 12 \times 12 \times 3.5 \\ = \frac{1}{3} \times 11 \times 12 \times 12 \\ = \frac{1}{3} \times 1584 \\ = 528$
