Please i need help

An ideal Otto cycle has a compression ratio of $8.$ At the beginning of the compression process, air is at $95$ kPa and $27$ C$,$ and $750$ kJ$/$kg of heat is transferred to the air during the constant$-$volume heat$-$addition process. Taking into account the variation of specific heats with temperature, determine $($a$)$ the pressure and temperature at the end of the heataddition process, $($b$)$ the net work output, $($c$)$ the thermal efficiency, and $($d$)$ the mean effective pressure for the cycle

Note: I have to use the constant specific heat method

and complete the table PR
