BMAT Mathematics Equations Q&A

Speed (m/s) = frequency (Hz) x wavelength (m) Arithmetic series Sn = n x (first + last)/2 N= common difference Nth term of an arithmetic sequence (a+(n-1)d) Nth term of a geometric sequence sn = a1 (1-rn) / (1-rn) Area of a rectangle/parallelogram b x h Area of a triangle A=1/2bh Area of a trapezium 1/2 ( a + b) d Area of a circle A=πr² Circumference of a circle 2πr Volume of a cube V=s^3 Volume of any uniform prism area of cross section x length Volume of a sphere 4/3πr³ Volume for a cone or pyramid 1/3 area x height Surface area of a cube 6s² Surface area of a regular prism 2(bh + lh + bl) Surface area of a hollow cylinder 2πrh Surface area of a solid cylinder 2pirh+ 2pir^2 Probability of a given event P(E) = number of times E occurs / total number of outcomes Speed = distance/time
