Solution
Degree of a polynomial is the highest power of the variable in the polynomial.
$(i)$ $5 x^{3}+4 x^{2}+7 x$
This is a polynomial in variable $x$ and the highest power of variable $x$ is $3 .$ Therefore, the degree of this polynomial is $3$ .
$(ii)$ $4-y^{2}$
This is a polynomial in variable $y$ and the highest power of variable $y$ is $2$ . Therefore, the degree of this polynomial is $2$ .
