## anonymous one year ago A cone has a diameter of 18 in. and a height of 14 in. What is the volume of the cone? Use 3.14 as an approximation for straight pi . Express your final answer in hundredths. in3

I'm not sure if you should convert imerial to metric units for calculation, but you should use the volume of cone formula: $V=\frac{1}{3} \pi r^2 h$

r=half of the diameter h=height

i got it now

What do you get?

5. anonymous

18990.72

Nope doesnt seem right, have you divide the diameter by 2?

$V=\frac{1}{3} \pi (\frac{18}{2})^2 (14)$
