The following histogram represents the heights of the students in Ari’s classroom. Identify at least three things that you can infer from the histogram about the distribution’s center, spread, and overall shape. (I’m so slow with thinking today, please help)

Hiya! 
The answers would be,
1.) The frequency seems to have a continuous rate of height 

2.) You can conclude that the age would continue to go up

3.) You can also conclude that the frequency would go down once the age goes up

Good-Luck!   ʕ•ᴥ•ʔ 

The measure of center is going to be mean and the spread is going to be standard deviation. The shape is going to be symmetric. Here's why: 

There are no outliers in the data. We can infer that by simply looking at the data within each inch range. Because there are no outliers, that means the data is symmetric. Because the data is symmetric (or nearly symmetric) we always use mean and the standard deviation as a measure of spread and center. 

but which cone!?

assuming you need volume of the complete solid,

113.04 ft³

volume of cone is 1/3 πr²h
