HELP ME ASAP TO DO THE MATH

Answer 1

Answer:

A = pi*(8 mm)^2 = 64*pi mm^2

Step-by-step explanation:

The formula for the area of a circle is A = pi*r^2, where r is the radius.  Thus, r^2 = (25pi) / pi, or 25, and r = 5 mm.

If we increase this radius by 3 mm, we get the new radius 8 mm.  The area of the new circle will thus be A = pi*r^2, or, in this particular case,

A = pi*(8 mm)^2 = 64*pi mm^2.
