angles in a triangle= ?
?= 180 degrees
area =
length * width
circle) A =
C =
A = pi * radius squared C = 2 * pi * radius
any shape) A =
A = Length * Width
triangle) A =
A = 1/2 base * height
any 3D shape) V =
V = Length * width * height
cylinder) V =
V = pi * radius squared * height
sphere) v =
V = 3/4 pi * radius cubed
cone) V =
V = 1/3 pi * radius squared * height
square based pyramid) V =
V = 1/3 length * width * height
