Question

2. FIND THE VOLUME OF A CONE 0F DIAMETER 14M AND HEIGHT 21CM. (TAKE = 3 ).

Answer 1

343
`\pi`

Explanation:

Volume of a cone is
`(1)/(3)`
`\pi`
`r^(2)`*h

If the diameter=14 and r=
`(diameter)/(2)` then r= 7

`7^(2)`= 49

49*21=1029

`(1029)/(3) = 343`

if it asks to round multiply 343 by pi and round
