Perimeter, Area and Volume Flashcards
Formula
The Trapezoidal Rule
A = 1/2h(d1+d2)
Area = 1/2 x height x (parallel lines added together)
Formula
Surface area of an open cylinder
SA = 2πrh
Surface Area = 2 x π x Radius x Height
Formula
Surface area of a closed cylinder
SA =2πr^2 + 2πrh
Surface Area = (2 x π x Radius^2) + (2 x π x Radius x Height)
Formula
Surface area of a sphere
SA = 4πr^2
Surface Area= 4 x π x Radis^2
Surface area of a closed hemisphere
SA = 3πr^2
Surface Area= 3 x π x Radis^2
Formula
Surface area of a cone
SA = πr^2 + πrl
Formula
How do you calculate the slant height of a pyramid’s faces?
A right angle triangle is formed by the height of the pyramid itself and the base.
Formula
Volume of a right prisim
V = Ah
Volume = Area of cross-section x Perpendicular height
Formula
Volume of a sphere
V = 3/4πr^3
V = 3/4 x π x Radius^3
Formula
Volume of pyramids/cones
V = Ah/3
V = Area x Height / 3
