measurements
surface area
sphere
A = 4 π r ^ 2
cone
A = π r s + π r ^ 2
cylinder
A = 2 π r h + 2 π r ^ 2
volume
cone
V = 1 / 3 π r ^ 2 h
sphere
V = 2 / 3 π r ^ 3
pyramid
V = 1 / 3 A h
circles
circumference C = 2 π r
A = π r ^ 2
arcs
radian measurements
arc length
l = sieta * r
capacity
1000 cm ^ 3 = 1000 m = 1 L
1 m ^ 3 = 1000 dm ^ 3 = 1000 L = 1000 kL
sectors
A = ( θ / 360 ) / π r ^ 2
