Answer:

8 meters.

Step-by-step explanation:

Let the 2 radii be x and 2x, then
π x^2 + π (2x)^2 = 80π

π x^2 + π 4x^2= 80π

x^2 + 4x^2= 80

5x^2 = 80

x^2 = 16

x = 4.

So the radius of the larger circle = 2*4 = 8 m.

Answer:

84 arrangements

Step-by-step explanation:

First, we need to calculate the total number of roses that the shop owner has. We do this by adding the pink roses and the red roses that the owner has.

342 + 330 = 672 total roses

Now that we have the total number of roses we simply divide by the number of roses needed for each arrangement (8) in order to calculate the total number of arrangements that the owner can make.

672 / 8 = 84 arrangements
