                           SOME IMPORTANT MATHEMATICAL FORMULA'S

Circle : Area = pie r2

; Circumference = 2 pie r.

Square : Area = x2 ;

 Perimeter = 4x.

Rectangle: Area = xy ;

Perimeter = 2(x+y).

Triangle : Area =1/2(base)(height) 
; 
Perimeter = a+b+c.

Area of equilateral triangle = 3/4a2
.
Sphere :

 Surface Area = 4 pie r2

 Volume =4/3 pie r3
.
Cube : 

Surface Area = 6a2

Volume = a3

Cone :

 Curved Surface Area = p rl 

Volume =1/3p r2h

Total surface area = . p r l + p r2

Cuboid : 

Total surface area = 2 (ab + bh + lh)

 Volume = lbh.

Cylinder :

 Curved surface area = 2 p rh

Volume = p r2h

Total surface area (open) = 2 p rh

Total surface area (closed) = 2 p rh+2 p r2 


HERE P STAND FOR PIE=3.14 OR  22/7
