20π or 62.8 roughly
Step-by-step explanation:
Hello!
The formula for finding the circumference of a circle is 2rπ:
In that case, all we have to do is substitute 10m for our r.
2 × 10 = 20.
So circumference will be 20π.
Using 3.14 for π:
We get that 62.8 is a rough estimate for the circumference.
Really, it's 62.831..... going on forever since π is irrational.
Thus, the answer exactly is .
Hope this helps!
Answer:
a) The variable of interest is the students' preferred way/method of study.
b) The variable of interest is a qualitative variable.
Step-by-step explanation:
a) The survey was setup to investigate the preferred way of study for students in Orange County Community College.
Hence, the variable of interest is the students' preferred way/method of study.
b) Since this variable of interest cannot take on numerical values, it can only be expressed in qualitative means (in the different ways that students study), the variable of interest is a qualitative variable.
Hope this Helps!!!
