Area calculation

Enter two values. Other values will be calculated.

 A rectangle.

Side a: Side b:

This calculator computes the values of a circle (radius, diameter, circumference or area) when one value is given.
 A circle.

Fill in one field. The others will be calculated.

Radius r:

Diameter d:

perimeter U:

Area A:

This calculator calculates from three values of a triangle all other values.
 A triangle.

Enter three values. Other values will be calculated.

a: b: c:
alpha : beta : gamma :
Height: ha: Height: hb: Height: hc:

Not often needed (let empty if not needed):
Median line:
sa: sb: sc:

Calculate a square

Enter one value. Other values will be calculated.


Calculating a rhomb

Enter two values. Other values will be calculated.

 A rhomb.
Side a:
Diagonal e: Diagonal f:
alpha beta

Enter one function in here.
Hint: Enter as 3*x^2 ,
as 3/5 and
as (x+1)/(x-2x^4)

Enter the other function in here.

To write powers, use ^. This means, you gotta write x^2 for .

If you got some information about your area, the question is how to calculate the other informations. In many cases this is possible. A square or a circle e.g. are already given by a single information (e.g. perimeter or area). Having areas with less symmetries means we need more information. Mathepower has many area calculors.
