Volume of a Cylinder, Cone, and Sphere We are learning to…find the volume of a cylinder, cone and sphere
Volume • Definition • The number of cubic units needed to fill a given space • Geometric Shapes • Cylinder • Cone • Sphere
Cylinder • A three dimensional figure with two parallel, congruent bases connected by a curved lateral surface • Volume of a Cylinder
Previous Formulas Learned Area and Circumference of a Circle Circumference is the perimeter (length outside) of a circle. Area is the space inside of an object.
Cylinder • Formula • B = Area of the base • h = Height • r = Radius • = Pi = 3.14159…..(irrational number use calculator unless told otherwise)
Volume of a Cylinder • Label the BASE and HEIGHT of the cylinder below: Height of the Cylinder! Base of the Cylinder!
Volume of a Cylinder • For the Volume of a Cylinder we can write: V = B(h) OR V = πr2(h)
Volume of Cylinders Class Practice 18 cm 5 cm
Volume of Cylinders Class Practice V= π(7²)(12) V= (3.14)(49)(12) 12 cm V= 1846.32 cm³ 7 cm

Cone • A cone is a 3-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex.
Cone • Formula
Homework • Practice handout on cones
Sphere • A three dimensional figure with all points the same distance from the center • Volume of a Sphere
Sphere • Formula
