What is the approximate volume of the cone? Use 3.14 for π.
OpenStudy (anonymous):
OpenStudy (anonymous):
A.
1206 cm3
B.
3260 cm3
C.
2170 cm3
D.
6510 cm3

I'm stomped between A and C
OpenStudy (campbell_st):
the formula for the volume of a cone is
\[V = \frac{1}{3} \times \pi \times r^2 \times h\]
reading the question you have been told to use
\[\pi = 3.14, ~~r = 12~~and~~h = 8\]
just substitute and then calculate the answer

must of miscalculated or something
OpenStudy (campbell_st):
so its
\[V = \frac{3.14 \times 12^2 \times 8}{3}\]
OpenStudy (anonymous):
Now i got this
31795.6
OpenStudy (campbell_st):
ok...
\[3.14 \times 12^2 \times 8 =3617.28\]
now divide the answer by 3
OpenStudy (anonymous):
I got 1205.76
