Around cookie cake, divided into 8 equal pieces, has a diameter of 16 inches. marty eats one piece of cake. what is the area of the piece of cake that marty eats? leave your answer in terms of pi. a)4π in2 b) 8π in2 c)16π in2 d) 64π in2

The piece that young Marty indulges in will be one-eigth the area of the entire cookie, since there are 8 equal pieces.
What is the area of the entire cookie cake?
The area of a circle is π*r²
The diameter is 16 inches, so the radius is 8 inches.
Area = π * 8²
Area = 64 π in²

The entire cookie has an area of 64 π in².
To find the area of Marty's piece, divide this number by 8:
64 π in² ÷ 8 = 8 π in²
