Important formula for Math’s

Its our pleasure to assist you towards your goal .for inbuilt quality Important formula may help you to get better performance in exam.


1. Triangle

Area= 1/2 b×h
b=base
h= height
Volume V= A×h
A= area
h= height


2. rectangular

Area = w×h
w= width
h= height
Volume V= L×H×W
L= Length
H= height
W= width


3.Trapezoid

Area = 1/2(a+b)×h
h= vertical height
a,b are the parrallel sides

Volume V= Area×Height between trapezium ends


4.Ellipse

Area= πab
a=half of minor axis
b=half of major axis

Volume V= 4/3 πabc


5.Square

Area= a2
a= length of side

Volume V= a3
a= lenth of side


6.Parallelogram

Area= b×h
b=base
h= vertical height

Volume V=area of base× height


7.Circle

Area= πr^2
r= raidus

Volume V=πr2h


8.Sector

Area= 1/2 r^2∅
r= radius
∅= angle in radius
