thanks jkme

the 1's tha can prolly help you are the 1s tha already took geometry.. meanin they prolly dun have the books..

jus ask the ?s and we'll try our best.

how do you find the volume of cylinder base and spherical/pyramidal top section??? :huh:

I think it's area of a cylinder( 3.14 x radius squared) plus area of a cone 1/3 x 3.14 x radius squared

Rite, its (pie)(r)(^2)

geometry? remember everything about geometry if you're going to take calculus later. cause some of that geometry stuff will come back and haunt you again. puhahahah....(?)

I think what ur talking about is a cone...
I'm pretty sure the volume for it is:

(1/3)pi*r^3

i think thats the area, though is it r^3? or r^2? I think it's squared not cubed. So it's (1/3)(pi)(r^2)


An easy way to remember it is this: Area of any cone of cylinder. Just remember, length times height is always the area in some form. Cylinder...take one of the bases, the area of that is the length, and multiply that by the height. So it's (pi)(r^2) * (height). Same for cones or pyramids except it's 1/3 of it.
