Answer:

Circumference= 43.96 feet

Step-by-step explanation:

Diameter of the circle= 14 feet

Radius of the circle= 14/2= 7 feet

Circumference of the circle= 2\pi r

As, \pi =\frac{22}{7}=3.14

Circumference:

                          =2*3.14*7\\\\=3.14*14\\\\=43.96feet

The circumference of the circle with the radius= 7 feet is 43.96 feet

The histogram below shows information about the number of books students read in a month:
max2010maxim [7]

Answer:

Option C is true - The number of students who read 4 books or fewer

Step-by-step explanation:

Here, to find the mean and median, we do not have proper information or specific values. We just have the ranges, so both the mean and median cannot be determined.  So, options A and B are not correct.

We can see two bins covering the 9 or more books, so option D cannot be true either.

Therefore, only option C is left and that is true.-  the number of students who read 4 books or fewer.
