Hola!
Circumference of circle is 12.56 cm
Means,
2 × π × r = 12.56
r = 12.56 × 3.14 × 2
r = 1.999 cm
According to Question,
Area of Circle:
π × r²
3.14 × 1.99 × 1.99
12.547 cm² = 12.56 cm² (approximately.)
Hence,
Area of Circle is 12.56 cm²
hope it helps!

There is a part of the equation missing so I can't solve completely
Women can be seated in 89 ways.
Let Sn be the number of possible seating arrangements with n women. Consider n≥3 and focus on the rightmost woman. If she goes back to her seat, then there are Sn−1 ways to seat the remaining n−1 women. If he is sitting in the penultimate seat, then the woman who was sitting there before must now sit in the rightmost seat.
This gives us Sn−2 ways to seat another n−2 woman, so we get the recursion Sn=Sn−1+Sn−2. Starting with S1=1 and S2=2 we can calculate S10=89.

8 goes in to 16 2 times so put 2 on the top. 8 x 2 is 16 so do 16 - 16 which is 0. 8 cant go into 0 so put a 0 on top. Bring down the 1; 8 cant go into 1 so bring down the 3. 8 can go into 13 1 time so put a 1 on top. 13 - 8 is 5 so the remainder is 5
You would start by 6÷3. This would tell you that for every proud of hamburger you pay $2.
Therefore multiply 10×2 and that equals 20.
Therefore, your answer is $20.
