Area of a circle is

$\pi {r}^(2)$
So,

$\pi r {}^(2) = 1915.6826 \\ {r}^(2) = (1915.6826)/(\pi) \\ r = √(609.7807104) \\ r = 24.69373828$
Diameter is twice the radius. So,
24.69373838 × 2 =49.38747657
=49.4 m ( 3 significant figures) or correct the answer to the amount of significant figures the question wants
