Answer:
4046.56 cm3
Step-by-step explanation:
The base is made by 5 isosceles triangles, with one side of 14 cm, and the opposite angle of 
. Each of the other angle is 
. From there, you can calculate the height of each base triangle as in 
or 9.634...cm.
Your volume will be 
This is solved for all values of
y = -x-3. (Assuming you meant that 2x+2y=-6).
V=hpir^2
h=4
r=1.25
v=4pi1.25^2
v=4pi1.5625
v=6.25pi
v=19.625
rounded to hundreth
v=19.63 ft³
Answer:
32.
Step-by-step explanation:
Correct answer: A
This represents single value, as we are given an estimate of a "certain amount" of the population. We can conclude that it helps determine / randomly selecting people from a survey.
