The shapes below that have a constant cross-section between a pair of faces are cylinder, cube, sphere, hexagonal, and prism.
<h3>What is the definition of geometry?</h3>
It is concerned with the geometry, region, and density of various 2D and 3D shapes.
A cylinder is a closed solid with two parallel circular bases and a curving surface connecting them.
The shapes have a constant cross-section between a pair of faces like a cylinder.
Hence,cylinder, cube, sphere, hexagonal, and prism are the forms below that have a constant cross-section between a pair of faces.

Answer:
The top angle of the triangle is, X = 68°.
Step-by-step explanation:
Let there is a triangle named PQR with bottom corner angles ∠ P and ∠ Q and the ∠ R is the angle at the top.
Now, given that ∠ P = 31° and ∠ Q = 81° and we have to find out ∠ R i.e. X.
In Δ PQR, we know, ∠ P + ∠ Q + ∠ R = 180°
⇒ 31° + 81° + X = 180°
⇒ X = 68°
Therefore, the top angle of the triangle is 68°. (Answer)
1a) 8 / (1/2) = 16 * 3 = 48
1b) 3sqrt(49) = 3 * 7 = 21
1c) (5+2)(-8) / (-2)^3 -3
(7*-8) / (-8 -3)
-56/-11
56/11
