Answer:
radius is 7 cm
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the volume is 1323 pi and the height is 27
1323 pi = pi r^2 * 27
Divide each side by 27 pi
1323 pi /27pi = pi r^2 * 27/ 27 pi
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 = r
Triangular Prism is incorrect because that moreover looks like a rectangular base with the sides of triangles. It's close but not quite. The square prism is the same thing, but except for triangles, they have a square like side and a rectangular base. A triangular pyramid has a base and sides or triangles. A square pyramid would most likely be the answer because it's sides consists of triangles whilst the square as it's base.
