Volume of a Cylinder, Cone, and Sphere We are learning tofind 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 http://www.youtube.com/watch?v=FLtkVS8bAUY Previous Formulas Learned Area and Circumference of a Circle Formula to find the area of a circle:
A r 2 Area is the space inside of an object. The formula to find the circumference of the circle: C d Circumference is the perimeter
(length outside) of a circle. Cylinder Formula 2
VV r h Bh 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: Base of the Cylinder!
Height of the Cylinder! Volume of a Cylinder For the Volume of a Cylinder we can write: V = B(h)
OR V = r2(h) Volume of Cylinders Class Practice V r 2 (h) V 3.14 5 18 cm 5 cm
