Write the coefficient of $x^{2}$ in the following polynomial:
$\pi x^{2}-\frac{22}{7} x+3.14$
$\pi x^{2}-\frac{22}{7} x+3.14$
(A) The given polynomial is $\pi x^{2}-\frac{22}{7} x+3.14$.
To find the coefficient of $x^{2}$,we look at the term containing $x^{2}$,which is $\pi x^{2}$.
The numerical factor multiplying $x^{2}$ is $\pi$.
Therefore,the coefficient of $x^{2}$ is $\pi$.
