Question

what are the formulas for the following..
1. pyramid
2. cylinder
3. prism
4. sphere
5. cone

Answer 1

give me one second..

Answer 2

ok

Answer 3

Prisms
Volume = Base X Height
v=bh
Surface = 2b + Ph (b is the area of the base P is the perimeter of the base)


Cylinder
Volume = pr2 x height
V = pr2 h
Surface = 2p radius x height
S = 2prh + 2pr2

Pyramid
V = 1/3 bh
b is the area of the base
Surface Area: Add the area of the base to the sum of the areas of all of the triangular faces. The areas of the triangular faces will have different formulas for different shaped bases.

Cones
Volume = 1/3 pr2 x height
V= 1/3 pr2h
Surface = pr2 + prs
S = pr2 + prs
=pr2 + pr

Sphere
Volume = 4/3 pr3
V = 4/3 pr3
Surface = 4pr2
S = 4pr2

Answer 4

did that help? can I have a medal?

Answer 5

Thanks hope that really helped!

Answer 6

your welcome and it didnt really help the answer choices are L.A.=pi.r.l, V=3/4pi.r^3, T.A=2pi.r.h.+2pi.r^2, V=1/3B.h, L.A.=p.h

Answer 7

so you where looking for something else then..oh.. ok

Answer 8

yeah

Answer 9

sorry
