We know that
circumference=pi*D
where
D is the diameter
D=91 cm
so
pi-----> is the value of the calculator------> 3.1415926535897932
circumference=pi*91------> 285.88 cm------> 285.9 cm
the answer is
285.9 cm
112 cm² * 6 triangles = 672 cm²
Because everything below 5 rounds down and everything about 5 rounds up 8.961 would round to 9.
Answer:
65%
Step-by-step explanation:
No, the events "drank coffee" and "drank tea" are not mutually exclusive, as there are 10% of employees drank both coffee and tea.
If there are 50% drank coffee and 10% of them enjoy both, then there are 40% of the employees enjoy only coffee.
Similarly, there are 15% of employees who only enjoy tea.
Then the probability of selecting a person who only enjoy tea or coffee is
40% + 15% = 65%
