Still kinda confused though, so number three, would it be p=62.5/78.5 ? ? it’s prob wrong but i would love some !

62.5 is the final answer

Step 1: Find the area of the shaded region using A=pi*r^2
A = pi*(8)^2 = 201.06

Step 2: Find the area of the whole circle (shaded + non)
A = pi*(10+8)^2 = 1017.88

Step 3: Find probability... P = 201.06/1017.88 = 0.20 is the Pr of dart hitting shaded region

Number nine is f(x)= 40x : ) hoped i ya
