Answer:
C = 56.6 cm
Step-by-step explanation:
The circumference of a circle is
C = 2 * pi *r
C = 2 * 3.142 * 9
C =56.556
Rounded to 1 decimal place
C = 56.6 cm
9514 1404 393
Answer:
(b) 112.2 ft
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
For the given geometry, this becomes ...
tan(65°) = (height above eye level)/(50 ft)
Then we have ...
(height above eye level) = (50 ft)tan(65°) = 107.2 ft
Adding the height of eye level will give us the height of the building.
building height = (eye level height) + (height above eye level)
building height = (5 ft) + (107.2 ft)
building height = 112.2 ft
