Find two separate volumes. You have a rectangular prism and a half cylinder.

formulas lol

Well, we just did the cylinder. Do the same as before and take half. For the rectangular prism. V=L*W*H or just multiply all sides

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
so i would do 6*9*11
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
witch in that case would be 594
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
Yes, that's just the volume for the rectangular prism. Now you'll have to find the volume for the half cylinder as well.

okay but no numbers are given for the base or hight of the half cylinder for me to find the volume
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
They are given. Just look.

what's V for cylinder again?
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
so base is 9 or 6 and height is 11
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
for a cylinder V= B*h
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
height is right, 11 base is wrong
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
base is not 9 or 6????

for the answer choices there is no pi in any of the answers.
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
No, remember B is area so in square units so mm^2, not just mm or one dimensional
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
but witch one would i use to square in order to get the base?? 9 or 6
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
pi is included inside the answer
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
neither try to find area of the base NOT a line!!
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
how would I do that????
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
you have half a cylinder so find the V like it's a full cylinder then to find the volume, take half of the full cylinder think of the base as a full circle
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
so i would times everything by 2 to get the full volume or wht
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
No, for cylinder the base is a circle find area of the circle
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
A=pi*r^2
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
to find area, you need?
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
okay but whats going to be the Radius in order to do that
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
Yes, you need the radius. Look at the picture.
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
It shows the diameter.
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
it would be half of 9 witch is 4.5
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
right, now find the area then the volume of the half cylinder then add V of half cylinder to V of rectangular prism and that's the answer
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
which if its 4.5 and you square that it would be 20.25pi
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
okay so the V of a rectagular prism is 594 and and the v of the half cylinder is 222.75 and i add that up it = to 816.75 witch is just 817 witch is not one of the choices
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
you miscalculated somewhere on the cylinder
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
I calculated the right answer. It's one of the choices.
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
i took 4.5^2 witch is 20.25 and that then becomes 20.25pi then i timed it by 11 and got 222.75
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
You did NOT account for half of the cylinder. You calculated it like it was a whole one. Take half of it.
 one year ago

Skittles10412 Group TitleBest ResponseYou've already chosen the best response.0
so i have to divide the answer 222.75 by 2
 one year ago

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
Of course, it's not showing a full cylinder.

hairynmad Group TitleBest ResponseYou've already chosen the best response.0
Vcyl=B*h B=pi*r^2=pi*4.5^2 h=11 Vrect=LWH=11*9*6 Total Volume=Vrect + 0.5*Vcyl
