Answer:
sorry.......dud.....
Step-by-step explanation:
hope some one will help you........
Use the distance formula for the 2 points and then halve the answer
I got 22 because if u do 20 multiplied by 10% that gives u 2 which u then add onto the 20 to get the starting price. 10% of 22 is 2 and then 22-2 = 20 (if u we’re doing it from the starting price)
I can’t type it out but the equation is Pi(radius)^2
