Answer:

A. Bar graph

Step-by-step explanation:

A bar graph is also known to be a bar chart. It is used to represent data such as quantities and numbers graphically. These data are represented in bars or strip.

The bar graph is best answer because, from the question a student could play more than a sport, therefore a student could belong to about two or more sports categories. This makes a bar graph more appropriate. Using pie chart would be misleading as students can belong to more than one category

I NEED HELP PLZ <br> What is length of PR <br> m PZR is 2/3 pie radius
dalvyx [7]

Answer:

Option (4)

Step-by-step explanation:

m(∠PZR) = \frac{2}{3}\pi

Radius of the circle = 8

Since, length of an arc = \frac{\theta}{2\pi }(2\pi r)

Here, θ = Central angle in radians

From the given formula,

m(arc PR) = \frac{\frac{2}{3}\pi}{2\pi }(2\pi \times 8)

                = \frac{2}{6}(16\pi )

                = \frac{16}{3}\pi

Therefore, Option (4) will be the correct option.
