Formula for Volume of a Cone

Result

1/3 π h r^2≈1.0472 h r^2
(assuming base radius r, height h, apex (0, 0, h), and base center (0, 0, 0))

Visual representation


(drawn with base radius 1 and height 2)

Properties of finite cone

slant height | sqrt(h^2 + r^2)
volume | 1/3 π h r^2≈1.0472 h r^2
lateral surface area | π r sqrt(h^2 + r^2)≈3.14159 r sqrt(h^2 + r^2)
base area | π r^2
base circumference | 2 π r≈6.28319 r
surface area | π r (sqrt(h^2 + r^2) + r)≈3.14159 r (sqrt(h^2 + r^2) + r)
angle | tan^(-1)(h/r) radians
(assuming base radius r, height h, apex (0, 0, h), and base center (0, 0, 0))
