3. Look at the cone above. If R = 3 cm and H = 3 cm, what is the approximate volume of the cone? (Use 3.14 for .) Cone Volume = (1/3)r2h 18.84 cm3 9 cm3 28.26 cm3 9.42 cm3 https://app30.studyisland.com/userfiles/ok8cone.gif

Plug the numbers into the volume formula: V = 1/3 * pi * r^2 * h = 1/3 * 3.14 * (3)^2 * 3 = ?

OpenStudy (therealmeeeee):

i got B

OpenStudy (ranga):

pi is missing from the volume formula in the problem as you typed it. B is not the answer.

OpenStudy (ranga):

Cone Volume = (1/3)(pi)r2h

OpenStudy (therealmeeeee):

oh its A

OpenStudy (ranga):

No. I showed the work above. Just use your calculator to multiply: 1/3 * 3.14 * (3)^2 * 3

OpenStudy (therealmeeeee):

C

OpenStudy (ranga):

yes.
