Answer:
15.1 to nearest tenth.
Step-by-step explanation:

Diameter = 2*8 = 16
Circumference = 3.14 (16), so the answer is C.
5. The question asking asking for the surface of the toy box.
Surface area of a cube = 6*the area of one face of the cube = 6 (edge * edge)
Substitute the edge with 2
Surface area of the toy box = 6(2*2) = 6(4) = 24
Surface area is 24 feet squared, so the answer is B
