Question

find the volume of a cone with a radius of 4 cm and a height of 10 cm

Answer 1

The formula for finding the volume of a cylinder is \[V=Bh\] B being the base. You'll start off by finding the area of the base with the formula \[\pi r^{2}\] then multiply by the height.

Answer 2

i got 150.24

Answer 3

doesnt look correct

Answer 4

its not

Answer 5

cuz, r^2*h itself comes to 16*10 = 160

Answer 6

if u multiply it wid pi, it wud be atleast 3 times more than 160

Answer 7

check ur calculation once

Answer 8

i got 1507.2

Answer 9

hey hang on, this is a cone ! not a cylinder

Answer 10

yea

Answer 11

ok, then use this formula :-

volume of cone = \(\frac{1}{3} \pi r^2 h\)

Answer 12

ok i got 167.47

Answer 13

thats right !

Answer 14

Thank You

Answer 15

np :) look at dan's its interesting integral for volume..

Answer 16

dont worry about my way its prolly ridiculously wrong! iam practicing

Answer 17

:)

Answer 18

:) its ok

Answer 19

its advanced it looks beautiful :)

Answer 20

hhahah i wanted to try something
