Cylinder: 1²(3) = 3
3(9) =27
Prism: 4x3x6 =72
Total: 72+27 = 99in³
Answer:

Step-by-step explanation:
The sum of the interior angles of any polygon with five sides is equal to
. Therefore, we can set up the following equation and solve for
:

Answer:
i think it's 13/16
Step-by-step explanation:
1/8 times 2 is 2/16 and 3/8 times 2 is 6/16 so add all up to get 13/16
15/10 = 18-x/x is the ratio of the larger to the smaller triangle
Cross multiply:
15x = 10(18 - x)
15x = 180 - 10x
25x = 180
x = 7.2
Plug back in to check
15/10 = 1.5
18-7.2/7.2 = 10.8/7.2 = 1.5 :)
