I want to perform a multivariable optimisation. where I want to minimise both the objective functions together for the same value of variables.
The objective function and the variables are listed in my attachment, please go through this once!
Thank you.

Please check the code for ineqality conditions. is it correct ? I'm not sure about the greater than and less than sign difference.
function [c,ceq] = nlcon_reg(x)
g = 9.8;
R = 0.15;
c1 = (-g*x(1)/(pi*R.^2)) + 0.001; % quality greater than 1.
c2 = (g*x(1)/(pi*R.^2)) - 0.03;
c3 = (-x(2)/2*R) + 0.75 ;
c4 = (x(2)/2*R) - 1.35 ;
c5 = -x(3)/x(2)+ 0.01 ;
c6 = x(3)/x(2)- 0.1 ;
c = [c1,c2,c3,c4,c5,c6];
ceq = []; % total time condition.
