3 0

Step-by-step explanation:

450 - 396 = 54

(54/450) * 100% = 12%

Hence the decrease is 12%.

3 0

Answer:

Step-by-step explanation:

The way to solve is to divide the number.

396/450 = 0.88 or 88%

Now, we subtract 88 from 100 to get 12, since we wanted the percent decrease.

Answer:

52pi

Step-by-step explanation:

You need the area of the large grey circle, minus the white circle, plus the small grey

Large grey = 8^2 * pi = 64pi

White = 4^2 * pi = 16pi

Small grey = 2^2 * pi = 4pi

64pi - 16pi = 48pi, 48pi + 4pi = 52pi
