Benutzt man bei umfang cm hoch 2?
Hey ich lerne gerade für eine mathe arbeit und habe eine Frage……
wenn ich den Umfang ausrechne muss ich bei dem Ergebnis dann cm hoch 2 schreiben????
und stimmt das dass man den umfang so rechnet?
So: 2•a + 2•b (je nach dem was für nh figur)
bitte nur direkte Antworten(:
No, size is a distance, length with cm
Areas have 2
should lead your circumferential calculation to 2, it is somewhere wrong
Ahh okay thanks
The size is a STRECKE, so no square. This is reserved for areas (length MAL width).
Thank you
No, you can use meters or centimetres on the circumference.
For volume : m3, cm3…

In a circle: r2 times Pi.
With a right-angle triangle, you can only calculate the third side with a2 +b2, and you need to drag the root from “c” (Pythagoras formula).
Thank you
Since when is the circumference of a circle πr2? The size is 2πr.
Sorry, my mistake – you’re absolutely right.
r2π is the area content. 2rpi.
Shame me for the confusion of the two circular formulas.
To my apology, I must say that I had pressed the school bench more than 40 years ago 😉
