Answer 1

Explanation:

Formula for the area of a circle of radius r is A = πr², where r is the radius.

Here, A = π(12 in)² = 144π in², or approximately 452.89 in².

Double check to ensure that you have copied down the possible answers correctly. Answer B would be correct if you were to insert π. (See above.)
