Answer:
172.70 sq. ft.
Step-by-step explanation:
The surface area of a circular cone is
r = radius of base l = slant height
r = 4.4 and l = 8.1

SA = 3.14(19.36) + 111.9096
= 60.7904 + 111.9096
= 172.70 sq. ft.
the student has left 75 because if you add 5 and 70 it gives you $75 that's how much the student had left.
