Maths Equations

• The volume of a sphere is calculated as (4/3)(pi)(r^3)
• The volume of a cone is calculated as (pi)(r^2)(h/3)
• The surface area of a sphere is (4)(pi)(r^2) also known as the differentiated version of the volume of a sphere
• The volume of a cylinder is (pi)(r^2)(h)
• v = u + at
• v^2 = u^2 + 2as
• s = ut + 0.5at^2
• s = vt - 0.5at^2
• s = 0.5(u + v)t
• Percentage error = absolute error / true value
• Absolute error is + or - half of the resolution
• If there is two sets of uncertainty (eg. on a ruler) multiply the absolute error by 2
