1. Given that a pizza with a radius of 4 inches has $N \%$ more area than a pizza with a radius of 3 inches. The integer closest to $N$ is ( ).
(A) 25
(B) 33
(C) 44
(D) 66
(E) 78
1. E.

From the problem, we know
$$
\frac{16 \pi-9 \pi}{9 \pi} \times 100 \%=\frac{7}{9} \times 100 \% \approx 77.78 \% \text {. }
$$

Therefore, the integer closest to $N$ is 78.
