Area of a Parallelogram

Multiply the base by the height
A = b x h
Area of a Trapezium

Area= ½ (a + b)h
Area of a Circle

Area = πr2
Circumference of a circle

Circumference = πD
Volume of a Cuboid

Volume = lwh
Total Surface Area

Total Surface Area = πrl + πr2
Volume of a pyramid

Volume = (1 3 means 1 3rd)
1 lwh
