aleksandr82 [10.1K]
ANSWER

The number of children between the ages of 9 and 15 who visited the park is
20


EXPLANATION


The number of children between the ages of 9 and 15 who visited the park are those within the age group 9 to 12 and 12 to 15.


We can from the graph that, the height of the bar that corresponds to the age group 9 to 12

= 14
and the height of the bar that corresponds to the age group 12 to 15

= 6


The sum of the two frequencies

= 14 + 6 = 20

Answer:

Part A) The volume of the entire cone is 168\pi\ in^3

Part B) see the explanation

Step-by-step explanation:

Part A) we know that

The volume of a cone is equal to

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

where

r is the radius of the base of the cone

h is the height of the cone

In this problem triangle ABD is similar to triangle ACE

Remember that If two figures are similar, then the ratio of its corresponding sides is proportional

so

\frac{AB}{AC}=\frac{BD}{CE}

substitute the given values

\frac{7}{14}=\frac{3}{x}

solve for x

x=14(3)/7\\x=6\ in

To find out the volume of the entire cone we have

r=CE=x=6\ in

h=AC=14\ in

substitute in the formula

V=\frac{1}{3}\pi (6)^{2}(14)

V=168\pi\ in^3

Part B) How did you determine the value for x in triangle ACE

In this problem triangle ABD is similar to triangle ACE

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

so

\frac{AB}{AC}=\frac{BD}{CE}

substitute the given values and solve for x
