Volume of a Cylinder

Base area times height.

V = π r^{2} h

Variables

Any prism or cylinder has volume equal to base area × height. A cone with the same base and height has one third of this volume.

$r = 3, h = 5$ : $V = 45 π \approx 141.4$ .

Find the volume and surface area of cubes, boxes, spheres, cylinders, cones and pyramids.

Area of a Circle

Area enclosed by a circle of radius r.
