Question

Find the volume of the right cone

Answer 1

Answer:

$384\pi cm^{3}$

Step-by-step explanation:

Height of cone(h) = 8cm

Radius of base(r) =12 cm

Slant height = 14.4 cm

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

Now putting values in formula

$\frac{1}{3} \pi *12^{2}*8$

$\frac{1}{3}\pi*144*8$

$\frac{1152}{3}\pi$

$384\pi$

Thus the volume of cone is $384\pi cm^{3}$

Hence Option A is correct.

Answer 2

Hi, thank you for posting your question here at Brainly. I hope I would be able to help you with my simple explanation:)

To calculate for the volume of a cone, the formula would be

V = 1/3*pi*r²*h

where r = 12 cm, h = 8 cm
So,

V = 1/3*pi*12²*8
V = 384*pi
