Here, 30/360 * 2πr = 10
1/12 * 2 * 3.14 * r = 10
r = 10*12 / 6.28
r = 19.11
Now, Area = 1/12 * 3.14 * (19.11)²
= 3.14/12 * 365.16
= 95.5 Ft²
In short, Your Answer would be Option C
Hope this helps!
Can you add an attachment to the table, so we can see the prices.
Each person will get a full brownie leaving you left over with 2 full brownies. You can cut both of the remaining brownies into 3rds giving you 6 pieces. Each person can then get 2 prices. This is 1 and 2/3 brownies per person
