This picture should help, i graphed it for you! : )
Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³
This can be represented by the inequality 8

x

12
As Dina wants at least 8, and no more than 12, that means 8, 9, 10,11, and 12, are applicable
Answer:
The voume of the cylinder is (pi)(x^2)(y)
Voulne of the cone is (1/3)(pi)(3x)^2(h). H is the unknown height of the con2
Since the volumes are equal
(pi)(x^2)y = (1/3)(pi)(9x^2)h
h= y/3
