Answer:
Part A) The volume of the entire cone is 
Part B) see the explanation
Step-by-step explanation:
Part A) we know that
The volume of a cone is equal to

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

substitute the given values

solve for x

To find out the volume of the entire cone we have


substitute in the formula


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

substitute the given values and solve for x
Answer:
Step-by-step explanation:
<u> </u>
3.4 or 3.4 repeating (3.4444444444444444444444∞)
and
3.44 rounded to the hundredth
a^2 evaluates to
a^2+a evaluates to
Multiply the exponent of a by 2giving
The answer is
a^2 evaluates to
+ =
The answer is
a^2+a+a^2 evaluates to
