35. Lateral Area of Prism = Perimeter of base * height\[=\left( 5+6+11.21 \right) \times 34\]
OpenStudy (paxpolaris):
to get the area of the base you could use heron's formula
OpenStudy (ruthless.753):
i dont know what that is
OpenStudy (ruthless.753):

Q35. A triangle with sides of length 5, 6, and 11.21 CAN NOT exist.
the longest side has to be smaller than the sum of the other two sides
OpenStudy (ruthless.753):
so whats the answer?
OpenStudy (paxpolaris):
39 . grain storage tank in the shape of a cone @Er.Mohd.AMIR
OpenStudy (ruthless.753):
i dont understand any of this
OpenStudy (paxpolaris):
35. the shape they have drawn cannot exist ... lol there CAN NOT be a right answer
i suppose they want you to assume its a right triangle for the base|dw:1463957578607:dw|

@PaxPolaris can you help me?
OpenStudy (paxpolaris):
39. surface area of a cone = \[\large \pi r ^2 + \pi r l = \pi r \left( r+l \right)\]|dw:1463958006109:dw|
\[r = 9\]\[h=54\]\[l^2=r^2+h^2\] so,\[l=9\sqrt{37}\]
OpenStudy (ruthless.753):
so whats that?

like the answer
OpenStudy (paxpolaris):
plug those numbers in the formula above to get the answer
OpenStudy (ruthless.753):
whats the length
OpenStudy (paxpolaris):
\[l = 9 \sqrt{37}\]
the answer for 39. is\[81 \pi + 81 \pi \cdot \sqrt{37}\]
OpenStudy (ruthless.753):
oh
