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 = 
Answer:
b. 14
Step-by-step explanation:
3x-15+2x-2
=5x-17
use the distribution property
The answer is 10 as the diameter because it says to estimate pi as 3. Since we know the circumference is 30 we can reverse it to find the diameter, since Circumference is pi time diameter.
