Answer:
Step-by-step explanation:
We are given the function:
and asked to find f(5). Therefore, we must substitute 5 in for each 
.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Multiply 18 and 5.
Add 90 and 11.
f(5) is equal to 101.
Area of a full circle is PI x r^2
Area = 3.14 x 8^2 = 200.96
Area of a sector is area * central angle / full circle
Area = 200.96 x 5PI/3 / 2PI = 160PI/3
Answer is C.
