Answer:
Option C (4096π in²)
Step-by-step explanation:
Area of the circle = 256π in²
We know that
, where r = radius of the circle
So,

Cancelling π from both the sides,


The radius of the circle = 16 in.
When the radius is multiplied with 4 , new radius = 16×4 = 64 in.
New Area = 
The answer is 1 because 7*9 is 63
7*10=70 70-7=63
