What is the formula for the surface area and volume of a Pyramid/cone

SA for Pyramid

2*l*/+l^2

l=length of base

/=slant height

Volume for Pyramid

1/3*B*h

B is area of base

SA for cone

3.14*r*/+3.14*r^2

/ equals slant height

Volume for cone

1/3*3.14*r^2*h

h is the height

Hope this helps!
