Answer:
The approximate area of one slice is 21.21 in².
Explanation:
Area = πr²
d = 18 in
r = 18 in/2
r = 9 inches
Solve for the area of the pie
A = π(9in)²
A = 81π in²
OR
A = 254.47 in²
Since the pie is cut into 12 slices, we will divide the area by 12
A = 81π in²/12
A = 6.75π in² ---in terms of pi
OR
A = 254.47 in²
A = 21.21 in²
