Look at the cone above. If r = 6 cm and h = 6 cm, what is the volume of the cone? (Assume = 3.14)
daser333 [38]

Answer:

226.08 cm³

Step-by-step explanation:

Hi!

To find the volume of a cone, you do 1/3 (3.14) × r² × h.

So all we have to do is substitute 6 in our r and h spots.

1/3 (3.14) × (6²) × 6.

= 1/3 (3.14) × 36 × 6.

= 226.08

Thus, the answer is \boxed{226.08{\text{\:cm\:or\:A}}}.

Hope this helps!
