Maths EOY Y8 Important notes

Formulae:

Area (Parallelogram) - B x H = area

Area (Trapezium) - (a + b) / 2 x H

Circumference - 2 x π x r OR C = 2(pie)r (C = 2 x (pie) x r (radius))

Diameter - d = 2r (diameter = 2 x radius)

Definitions

Area - the product of the base multiplied bu the height

Circumference = the distance around the circle, or the perimeter of a circle

Diameter =
