Original Circle Area = 45
A = pi r^2
Plug in what we know:
45 = 3.14 r^2
Divide 3.14 to both sides:
14.3312102 = r^2
Find the square root of both sides:
r = 3.78565849
Find 2/3 of this:
2/3 3.78565849 = 2.52377233
So this is the radius of the newly dilated circle.
A = pi r^2
A = 3.14 2.52377233^2
A = 3.14 6.36942677
A = 20
So the area of the newly dilated circle is 20 square inches.
