Question 7334
Assuming you meant this: {{{T=2*(pi) sqrt(L/g)}}}, then we can re-arrange to


{{{T/(2*pi) = sqrt(L/g)}}} or...
{{{sqrt(L/g) = T/(2*pi)}}} --> square both sides to give
{{{L/g = T^2/(4*(pi)^2)}}}


ok, now move g up to the other side, move the {{{T^2}}} term to other side and also the {{{4*(pi)^2}}} term too, so you have:


{{{(4L*(pi)^2)/T^2 = g}}}


OK, so now put the values in:


{{{g = (4L*(pi)^2)/T^2}}}
{{{g = (4*37.1*(pi)^2)/(1.26)^2}}}

{{{g = (148.4*(pi)^2)/1.5876}}}


so g = 922.5556 to 4dp (or 7 sf)


OK?
