Answer:
A = 20.25π sq meters
Step-by-step explanation:
C = 2πr
9π = 2πr
divide π from each side to get:
9 = 2r
r = 9/2 or 4 1/2
A = πr²
A = π (4.5²)
A = 20.25π
Total ratio = 4+7 = 11
33/11 = 3
4x3 = 12
7x3 = 21
so the two groups are 12:21
which is also = 4:7
You would round the hundreds.
but it depends what numbers there are of population like if you get into thousands round by thousand hundreds equals round by hundreds.
Median means middle so the middle num is 47 glad to help!
