P\u00e5 den h\u00e4r sidan kommer du att f\u00e5 l\u00e4ra dig att r\u00e4kna p\u00e5 lite olika l\u00e5dmodeller. L\u00e4s g\u00e4rna sidan om kantreflektioner f\u00f6rst.<\/p>\n\n\n\n

Radien = R
Omkretsen = O

Diametern = O \/ pi
Omkretsen = R x (2 x pi)
Ytan = pi x R^2<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Nu kan du r\u00e4kna ytor, omkretsar och annat kul.
 
Volymen i en l\u00e5da = h\u00f6jd x bredd x l\u00e4ngd

Om du anger m\u00e5tten i decimeter f\u00e5r du volymen i liter.

Ett exempel.
Vi har m\u00e5tten 23 x 23 x 23 cm.
Om vi s\u00e4tter in de m\u00e5tten, i decimeter, i formeln, ser den ut s\u00e5 h\u00e4r:
2,3 x 2,3 x 2,3 = 12,17 liter.
 
Om du anv\u00e4nder centimeter m\u00e5ste du dela resultatet med 1000 f\u00f6r att f\u00e5 volymen i liter.<\/p>\n\n\n\n
