You either wrote it down wrong, or there's a graphic to go along with it that you didn't include. There is not enough information to answer this question, sorry.
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:
<u>5%</u>
Step-by-step explanation
50/32= 1.56yard per second ; 50/31= 1.61 yard per second
1.61-1.56= 0.05* 100= 5%
2x - 5x + 4 = 0
- 3x = - 4
x = 4/3
