The circle is being dilated by a factor of 8 so the radius will be 8 times the original radius (4 ft).
The circumference of a circle =

, so if r is replaced by

we get

or just

.
Basically the circumference will be 8 times the original circumference.
If you plug in the original radius, into this new formula you get

The area of a circle =

, so if r is replaced by

we get

or just

Basically the area will be 64 times the original area.
If you plug in the original radius into this new formula you get

The answers are A, C, F, G, and H
