Use Matlab to answer the following question

4. In this example, we will try to plot a dome similar to the US Capitol dome. If we assume x andy values range between -10 m and 10 m from the center of the dome, and radius R is 7 meter, we can use sphere formula to plot the dome: We will need to reformat this equation to return z as a function of x and y, so As you know, z- cannot take negative values, so if you saved z under name z2 use the command z2( z2
