First we should figure out the volume of the prism (ignoring the cylinder at the moment)
(base * height/2)*depth
We need to find the height of the triangle which can be done with pythagoras because this is a right angled triangle (as shown by the little square at the bottom)
12 is the hypotenuse.
√12²-10² =6.63 (rounded)
Now we have the height of the triangle and can find the volume.
12*6.63/2*15=596.7
Now we find the volume of the cylinder.
area of circle * depth
area=3.14*1.5²
3.14*2.25
7.065
7.065*15=105.975
Now we subtract the volume of the cylinder from the volume of the prism and you have:
596.7-105.975
490.725 which is your answer
Hope this helps :)
See could have got the correct answer because if there was more numbers in the decimal you can round it to get .34 or because both answers have 12.3 and it doesnt matter about the other numbers after 3
Answer:
y - 9 = 8
y = 17
Step-by-step explanation:
3"11 + 4"8
If you add them you would get 7"19 which can't happen so you would take 12 of the inches out of 19 and make it another foot leaving you at 8"7
Combined, the two boxes are eight foot seven
-x+xy +4xy-x2
-2x2+5xy
C.-2x2+5xy
