Answer:

The volume of the figure is (\frac{l^{3}}{3})[\frac{\pi }{2}-1]\ units^{3}

Step-by-step explanation:

we know that

The volume of the figure is equal to the volume of the cone minus the volume of the square pyramid

step 1

Find the volume of the cone

The volume of the cone is equal to

V=\frac{1}{3}\pi r^{2}h

we have

r=\frac{l\sqrt{2}}{2}\ units ----> the diagonal of the square base of pyramid is equal to the diameter of the cone

h=l\ units

substitute

V=\frac{1}{3}\pi (\frac{l\sqrt{2}}{2})^{2}(l)

V=\frac{1}{6}\pi (l)^{3}\ units^{3}  

step 2

Find the volume of the square pyramid

The volume of the pyramid is equal to

V=\frac{1}{3}Bh

where

B is the area of the base

h is the height of the pyramid

we have

h=l\ units

B=l^{2}\ units^{2}

substitute

V=\frac{1}{3}l^{2}(l)

V=\frac{1}{3}l^{3}\ units^{3}

step 3

Find the volume of the figure

\frac{1}{6}\pi (l)^{3}\ units^{3}-\frac{1}{3}l^{3}\ units^{3}=(\frac{l^{3}}{3})[\frac{\pi }{2}-1]\ units^{3}

Sam kept track of the number of problems he was assigned for his math homework on the box plot.
yulyashka [42]

Answer:

Statement A is correct about Sam's box and whisker plot.

Step-by-step explanation:

We have been given a box plot and we are asked to find out true statement according to the box plot.

Since we know data represented by box plot is divided in four equal parts.

Upon looking at our box plot we can see that our data is symmetric. It's median is 15, which means half the math assignments have less than 15 problems and half of the math assignments have more than 15 problems.

Interquartile range represents 50% values of data and it is the difference between upper quartile and lower quartile. IQR is not affected by outliers.

IQR=Q_3-Q_1

Upon substituting given values from box plot we get,

IQR=19-11=8

From IQR we can conclude that half of the assignments contained 15 problems or fewer.Therefore, option A is the correct choice.
