Mensuration formula sheet part 3/7

Recommended Posts

NOTE: L=LENGTH B=BREATH R=RADIUS D= DIAMETER ^2=SQUARE

 

Area of a Circle (A) = pie x radius^2 / pie x diameter^2 x 1/4

 

Where r = radius of the circle and d = diameter of the circle.

 

 

Circumference of a Circle = 2 x pie x radius = pie x diameter

 

r= radius of circle

 

d= diameter of circle

 

 

Total surface area of cuboid = 2( LB + LH + BH)

 

where l= length , b=breadth , h=height

 

 

Total surface area of cuboid = 6(length)^2

 

where l= length

 

 

length of diagonal of cuboid = Under Root( L^2 + B^2 + H^2)

 

 

length of diagonal of cube = Under root(3 x length)

 

 

Volume of cuboid = L x B x H

 

 

Volume of cube = L x L x L
