Answer 2

why didnt u medal me

Answer 3

find the area of each

Answer 4

subtract the larger area from the smaller

Answer 5

@liana1026 why

Answer 6

then take the ratio of the difference of the areas to the total area
that is all

Answer 7

actually i should have said "subtract the smaller from the larger" sorry

Answer 8

why did @Study_together get medal i did two problems @liana1026

Answer 9

does anyone know the answer pleaseeeeeeee

Answer 10

Remember area of a circle is
\[A=\pi r ^{2}\]

Answer 11

okay

Answer 12

36%

Answer 13

Since the area of a circle is related to the square of the radius, just square both radii.
Then divide the smaller number by the larger number and multiply by 100.
That gives you what percentage of the area of the large circle is the area of the small circle.
Then subtract that percentage from 100%.

Answer 14

thanks

Answer 16

5*5*3.14=78.5 4*4*3.14=50.24
50.24/78.5=.64 1-.64=.36 so 36%

Answer 17

4^2 = 16
5^5 = 25
16/25 * 100 = 64%
100% = 64% = 36%
