lets start with 17, its a known property of trapezoids that \[st=\left( \frac{ wx+zy }{ 2 } \right)\], this will give you the lenth of the midsegment
OpenStudy (anonymous):
okay
OpenStudy (anonymous):
wait so 15+ 27 /2?
OpenStudy (worlddomination):
yep
OpenStudy (anonymous):
okay

what about the next one
OpenStudy (worlddomination):
go with this formula(V=πr2h 3
OpenStudy (anonymous):
so for 17 the answer is 21?
OpenStudy (anonymous):
and i can't see the formula you posted
OpenStudy (anonymous):
|dw:1427813788928:dw| we know that the radius is 2in as given by the picture. We also know that the outside the circle part is an isosceles triangle so both legs are the same length of 3, so now you know the lengths of all sides of the quadrilateral

oh it is volume equals TT r h/2 3
OpenStudy (anonymous):
@worlddomination there is nothing about volume in these problems
OpenStudy (worlddomination):
oh sorry i got distracted
OpenStudy (anonymous):

OpenStudy (worlddomination):

what do you don't get
OpenStudy (anonymous):
@worlddomination depends what youre finding the volume of
OpenStudy (worlddomination):
it doesn't matter i am looking straight in my book and that's what i got volume or not volume it is the same
OpenStudy (anonymous):
for 19 you use the properties of an isosceles triangle to find the angle. |dw:1427814219238:dw|
