Find the x-intercepts of y = 4x2 – 2x – 5.
First off, remember that finding the x-intercepts means setting y equal to zero and solving for the x-values, so this question is really asking...
VOLUME OF THE CONE
If, r=radis of the cone
h= perpendicular height
Then,
1)The volume of the cone =( 1/3 )πr2h
Ex- If,r=14 cm, h=15cm, then
1)The volume of the cone =( 1/3 )πr2h
