1 in 48 because only 48 are continental
Answer:
116 cm²
Step-by-step explanation:
Shaded Area = area of the larger circle - area of the smaller circle
Area of the larger circle = πr²
Where,
r = 6.5 cm
Area = π*6.5² = 42.25π cm²
Area of smaller circle = πr²
Where,
r = 2.3 cm
Area = π*2.3² = 5.29π cm²
✔️Shaded area = 42.25π - 5.29π = 36.96π = 116.113264
Area = 116 cm² (3 S.F)

The explicit formula
First, calculate 
Set n=2; So:
Substitute -25 for 
Calculate the common difference (d)
So, the nth term is:
Open bracket

OK Bctoscano. So first you have to take out the biggest number you can take out, so that would be 910, so 910 <em /><em /><u />divided by 7 is 130 because 700 divided by 7 is 100 and 210 divided by 7 is 30. Now what you have left is 38. The biggest amount I could take out is 35 so, 35 divided by 7 is 5. Now we have 3 left so the answer is 130 + 5 r.3 so 135 r.3.
