If it were a complete circle, its circumference would be
(π) x (diameter) = (π) x (2R) = 70 π inches .
Since it's only half of the circle, the length of the curved part is
70 π / 2 = 35 π = <em>109.9 inches</em> .
Can you list the answer choices?

Answer:
the sample proportion is higher
Step-by-step explanation:
What we must do is calculate the proportion of the population, we are left with the fact that out of 38 students 58% have cell phones, these are the proportion of the population, then they would be:
38 * 58% = 22.04 students
Now, the sample proportion is 24.
Therefore 22.04 < 24
Which means the sample proportion is higher
Answer: C is the correct option
Step-by-step explanation:
In four hours, a hiker in a canyon goes from 892 ft to 256 ft above the canyon floor.
From the above information,
Total distance travelled by the hiker in moving from 892 ft to 256 ft above the Canyon is 256 - 892 = -636 ft
Speed = distance travelled/time
The hiker’s vertical speed is total distance travelled vertically divided by the time it takes to travel the vertical distance. It becomes
-636/4 = –159 ft/h
