Volume, Area & Surface Area Flashcards
1
Q
Volume of a sphere
A
4/3 x π x r³
2
Q
Surface area of a sphere
A
4πr²
3
Q
Volume of a pyramid/cone
A
1/3 x base area x vertical height
4
Q
Surface area of a cone
A
(πr²) + (πrl)
[πr² is the base, πrl is the curved surface area]
5
Q
Volume of a cylinder
A
πr² x h
6
Q
Surface area of a cylinder
A
(2πrh) + (2πr²)
[2πrh being the curved surface area, 2πr² being the two bases]
7
Q
Area of curved surface (on a cone)
A
πrl
