SPORTS ARBITRATION DAY

On the 10th&11th April 2012, my LOVELY school, SMIAMAN held a Sports Arbitration Day.
Most of my beloved students took part in all activities on the day such as 
100 m sprint, 400 m & long jump. Ah, I felt so energetic...and tired.The events started at 
8.00 a.m and ended at 2.30 p.m.. Woah, such a lovely day.

Oops, some pictures on that day...

SOLID GEOMETRY III

Solid Geometry is the geometry of three-dimensional space, the kind of space we live in ...

Three Dimensions

It is called three-dimensional, or 3D because 

there are three dimensions:width, depth and height

 Cube (Hexahedron)

• It has 6 Faces  
• Each face has 4 edges, and is actually a square
• It has 12 Edges
• t has 8 Vertices (corner points)
• Surface Area = 6 × (Edge Length)²
• ^{Volume = (Edge Length)3}

Cylinder

• It has a flat base and a flat top
• The base is the same as the top, and also in-between
• It has one curved side
• Surface Area = 2 × π × r × (r+h)
• Volume = π × r² × h

Cone

• It has a flat base
• It has one curved side
• Surface Area of Base = π × r
• Surface Area of Side = π × r × s
• Volume = π × r² × (h/3)

Sphere

• It is perfectly symmetrical
• It has no edges or vertices (corners
• All points on the surface are the same distance from the center
• Surface Area = 4 × π × r²
• Volume = (4/3) × π × r³

h = 3rπ

PerNiaGaan Runcit kecil-kecilan & besar-Besaran

• Perniagaan runcit - membeli barang drpd pengeluar dan menjualnya kpd pembeli dalam kuantiti yg kecil
• Perniagaan besar-besaran - membeli secara pukal drpd pengeluar dan menjualnya kpd peruncit
