$c(P)$ and volume $(V)$ during the release $of$ a gas from $an$ accumulator

follows a law whereby $P=0*2V^{-1*2}$

$i.$ Use the Trapezoidal rule $to$ determine the work done $in$ Joules when the

volume $of$ gas $is$ expanded from $10{10}^{-6}{m}^{3}to100{10}^{-6}{m}^3$

$ii.$ Confirm $an$ exact answer $to$ part $(i)by$ applying calculus integration.
