Question

How do I find the volume of this cone?

Answer 1

(1/3) * pi * r2 * h

where:
pi = constant 3.14159...
r = radius of base
h = vertical height
l = length of 'slant' edge of cone.

Answer 2

the formula is

\[V = 1/3 \pi r^2h\]

in your question r = 30 and h = 60

substitute them into the formula and evaluate

Answer 3

volume-of-a-cone = (1/3) * (height) * (area-of-base)

so, volume V=
\[V= \frac13 \pi r^2 h\]

Answer 4

you got h=60, and r=30

plug in thevalues, calculate and enjoy!! (and don't forget the correct units)

Answer 5

Thanks, guys!
