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.
5(x-4)(x+2)
if you need to expand it, it would be 5(x²-2x-8)=5x²-10x-40=0
