ACKNOWLEDGEMENT I, Tarun Sharma of class x-c, completed this power point presentation about SURFACE AREAS AND VOLUMES under the guidance and supervision of Mr. Birbal Sir with a lots of useful and valuable formulae and geometric 3Dimensional shapes.

PowerPoint Presentation:

CONE

PowerPoint Presentation:

Curved Surface Area of a cone: П rs Total Surface Area of a cone: П rs + П r 2 Surface area

PowerPoint Presentation:

Volume of a cone: 1/3 П r 2 h volume

PowerPoint Presentation:

CUBOID

Surface area:

Surface area Total Surface Area of a Cuboid: 2(lb +bh +lh) Curved Surface Area of a Cuboid: 2( bh +lh)

VOLUME:

VOLUME Volume of a Cuboid: length × breadth × height

PowerPoint Presentation:

CUBE

Surface area:

Surface area Curved surface area of a cube: =4×side 2 Total surface area of a cube: =6 ×side 2

VOLUME:

VOLUME Volume of a cube: side 3

PowerPoint Presentation:

CYLINDER

Surface area:

Surface area Curved surface area: 2 П rh Total surface area: П rh +2 П r 2 =2 П r( h+r )

VOLUME:

VOLUME Volume of a cylinder: П r 2 h

PowerPoint Presentation:

Sphere

SURFACE AREA:

SURFACE AREA Surface area of a sphere: 4 П r 2

VOLUME:

VOLUME Volume of a sphere: 4/3 П r 3

PowerPoint Presentation:

Hemisphere

SURFACE AREA:

SURFACE AREA Curved surface area of a hemisphere: 2 П r 2 Total surface area of a hemisphere: 3 П r 2

VOLUME:

VOLUME Volume of A cube: 2/3 П r 3

PowerPoint Presentation:

FRUSTUM

SURFACE AREA:

SURFACE AREA Curved Surface Area Of A Frustum: П( r+R )l Total Surface Area Of A Frustum: П( r+R )l + П r 2 + П R 2 =П( r+R )l + П (r 2 + R 2 )

VOLUME:

VOLUME Volume Of A Frustum: 1/3 П h(r 2 +R 2 +Rr)
