The circumference of a circle:
C = 2 r π
If r = 5.1 cm:
C = 2 · 5.1 · 3.14 = 32.028 cm ≈ 32.03 cm
Answer:
The approximate value of the circumference is 32.03 cm ( rounded to the nearest hundredth ).
ANSWER
The length of the shadow is 49 ft to nearest feet.
EXPLANATION
We can find the length of the shadow using the tangent ratio.
Recall that,

From the diagram, the length of the shadow is the side of the triangle that is adjacent to the 27° angle

This implies that,

16 divided by 1
is 16 with remainder 0
= 16 R 0
= 16 0/1
Answer: The greatest distance, in feet is the first one 3ft.
False
The correct product has 3+1=4 decimal digits: 3.6693
